This patch series adds a new infrastructure for CMake packages called
CMAKETARGETS. It is based on the AUTOTARGETS infrastructure.

Changes in v2:

 * The toolchain-file is now also used by Buildroot for internal packages.
   This means less code duplication.

 * Add CMAKE_C/CXX_FLAGS, CMAKE_PROGRAM_PATH and CMAKE_INSTALL_SO_NO_EXE
   to the toolchain-file.

 * Remove CMAKE_{EXE,SHARED,MODULE}_LINKER_FLAGS from the
   infrastructure. CMake packages should use FIND_LIBRARY() or
   FIND_PACKAGE() and not rely on -L flags. If a package fails to build
   without -L, fix the package. Or add needed -L flags on a per package basis.

 * Move CMAKE_TARGET_{CC,CXX,CFLAGS,CXXFLAGS} variable initialization from
   package/Makefile.cmake.in (CMAKETARGETS_INNER macro) to package/Makefile.in.

 * Add a $(2)_BUILDDIR variable so that we can split build dir and
   source dir. $(2)_BUILD_DIR currently points to $(2)_SRCDIR to behave like
   the autotools infrastructure.

 * Remove -Wno-dev from configure options so that build system warnings
   are displayed. (Warnings should get fixed, so don't hide them.)

NOTE: The doc is (still) more or less a copy of of the autotools stuff. I don't
know how many build infrastructures Buildroot can have before the doc is
better off being refactored a bit so that the each build system is more about
what's different instead of repeating a bunch of stuff.

NOTE: There is no mention of the toolchain-file and how it can be used for
building packages outside of Buildroot in the doc. As the documentation
currently focuses on *integrating* packages in Buildroot, I didn't find a
suitable place for it. Is this ok for now?

NOTE: ccache needs testing

Thanks to Samuel Martin and Thomas Petazzoni for the comments on v1.

Comments also welcome on v2 :-)

A CMake toolchain-file makes it easy to develop CMake-based packages
outside of Buildroot. Just give the toolchain-file to CMake via the
-DCMAKE_TOOLCHAIN_FILE=... option.

Could you also add:

+       set(ENV{PKG_CONFIG_SYSROOT_DIR} $(STAGING_DIR))\n\

This is needed to get CMake pkg-config module to work properly.

I am not entirely happy with the name/location of the CMake toolchain
file, but that's something we can sort out later.

I have tested your patchset with my qserialport library (that uses
CMake as its build system and relies on Qt) and my custom application
(that uses CMake, Qt and qserialport), and it worked fine with  the
PKG_CONFIG_SYSROOT_DIR change mentionned above.

So, once this change is done, your patch gets my:

Thanks for the tip.

Or now, if you want :-)  I'm open for suggestions.

Great!

By the way, how are 'acked-by's handled? Do I add them to every patch
in the next series?

You're welcome. Thanks for doing this work in the first place.

I don't have suggestions at the moment. It's related to the future SDK
thing, which isn't completely well-defined at the moment. I'd say let's
keep it how it is for now, unless someone comes up with a better
location/name. We can always change it later on when we have a clearer
idea of what this SDK thing will look like.

Yes, exactly.

Thanks again!

The CMAKETARGETS infrastructure makes adding CMake-based packages to
Buildroot easy. It uses the same set of variables as the autotools
infrastructure, except for autoreconf and libtool stuff which is not
needed. Usage: just call CMAKETARGETS instead of AUTOTARGETS.

for host packages. I think, like for autotools packages, it is more
technically correct to set the installation prefix to $(HOST_DIR)/usr
rather than /usr.

Yes, I agree. I'll make this change in the next series.

+
+    <p>On line 6, we declare the version of the package.</p>
+
+    <p>On line 7 and 8, we declare the name of the tarball and the location
+    of the tarball on the Web. Buildroot will automatically download the
+    tarball from this location.</p>
+
+    <p>On line 9, we tell Buildroot to install the package to the staging
+    directory. The staging directory, located in <code>output/staging/</code>
+    is the directory where all the packages are installed, including their
+    development files, etc. By default, packages are not installed to the
+    staging directory, since usually, only libraries need to be installed in
+    the staging directory: their development files are needed to compile
+    other libraries or applications depending on them. Also by default, when
+    staging installation is enabled, packages are installed in this location
+    using the <code>make install</code> command.</p>
+
+    <p>On line 10, we tell Buildroot to also install the package to the
+    target directory. This directory contains what will become the root
+    filesystem running on the target. Usually, we try not to install header
+    files and to install stripped versions of the binary. By default, target
+    installation is enabled, so in fact, this line is not strictly
+    necessary. Also by default, packages are installed in this location
+    using the <code>make install</code> command.</p>
+
+    <p>On line 11, we tell Buildroot to pass custom options to CMake when it is
+    configuring the package.</p>
+
+    <p>On line 12, we declare our dependencies, so that they are built
+    before the build process of our package starts.</p>
+
+    <p>Finally, on line line 14, we invoke the <code>CMAKETARGETS</code>
+    macro that generates all the Makefile rules that actually allows the
+    package to be built.</p>
+
+    <h4 id="cmake-reference">Makefile for CMake packages : reference</h4>
+
+    <p>The main macro of the CMake package infrastructure is
+    <code>CMAKETARGETS</code>. It has the same number of arguments and the
+    same semantic as the <code>GENTARGETS</code> macro, which is the main
+    macro of the generic package infrastructure. For CMake packages, the
+    ability to have target and host packages is also available.</p>
+
+    <p>Just like the generic infrastructure, the CMake infrastructure
+    works by defining a number of variables before calling the
+    <code>CMAKETARGETS</code> macro.</p>
+
+    <p>First, all the package metadata information variables that exist in the
+    generic infrastructure also exist in the CMake infrastructure:
+    <code>LIBFOO_VERSION</code>, <code>LIBFOO_SOURCE</code>,
+    <code>LIBFOO_PATCH</code>, <code>LIBFOO_SITE</code>,
+    <code>LIBFOO_SUBDIR</code>, <code>LIBFOO_DEPENDENCIES</code>,
+    <code>LIBFOO_INSTALL_STAGING</code>, <code>LIBFOO_INSTALL_TARGET</code>.</p>
+
+    <p>A few additional variables, specific to the CMake infrastructure,
+    can also be defined. Many of them are only useful in very specific
+    cases, typical packages will therefore only use a few of them.</p>
+
+    <ul>
+      <li><code>LIBFOO_SUBDIR</code> may contain the name of a subdirectory
+      inside the package that contains the main CMakeLists.txt file. This is
+      useful, if for example, the main CMakeLists.txt file is not at the root
+      of the tree extracted by the tarball. If <code>HOST_LIBFOO_SUBDIR</code>
+      is not specified, it defaults to <code>LIBFOO_SUBDIR</code>.</li>
+
+      <li><code>LIBFOO_CONF_ENV</code>, to specify additional environment
+      variables to pass to CMake. By default, empty.</li>
+
+      <li><code>LIBFOO_CONF_OPT</code>, to specify additional configure
+      options to pass to CMake. By default, empty.</li>
+
+      <li><code>LIBFOO_MAKE</code>, to specify an alternate <code>make</code>
+      command. This is typically useful when parallel make is enabled in
+      the configuration (using <code>BR2_JLEVEL</code>) but that this
+      feature should be disabled for the given package, for one reason or
+      another. By default, set to <code>$(MAKE)</code>. If parallel building
+      is not supported by the package, then it should be set to
+      <code>LIBFOO_MAKE=$(MAKE1)</code>.</li>
+
+      <li><code>LIBFOO_MAKE_ENV</code>, to specify additional environment
+      variables to pass to make in the build step. These are passed before
+      the <code>make</code> command. By default, empty.</li>
+
+      <li><code>LIBFOO_MAKE_OPT</code>, to specify additional variables to
+      pass to make in the build step. These are passed after the
+      <code>make</code> command. By default, empty.</li>
+
+      <li><code>LIBFOO_INSTALL_STAGING_OPT</code> contains the make options
+      used to install the package to the staging directory. By default, the
+      value is <code>DESTDIR=$$(STAGING_DIR) install</code>, which is
+      correct for most CMake packages. It is still possible to override
+      it.</li>
+
+      <li><code>LIBFOO_INSTALL_TARGET_OPT</code> contains the make options
+      used to install the package to the target directory. By default, the
+      value is <code>DESTDIR=$$(TARGET_DIR) install</code>. The default
+      value is correct for most CMake packages, but it is still possible
+      to override it if needed.</li>
+
+      <li><code>LIBFOO_CLEAN_OPT</code> contains the make options used to
+      clean the package. By default, the value is <code>clean</code>.</li>
+    </ul>
+
+    <p>With the CMake infrastructure, all the steps required to build
+    and install the packages are already defined, and they generally work
+    well for most CMake-based packages. However, when required, it is
+    still possible to customize what is done in any particular step:</p>
+
+    <ul>
+      <li>By adding a post-operation hook (after extract, patch, configure,
+      build or install). See the reference documentation of the generic
+      infrastructure for details.</li>
+
+      <li>By overriding one of the steps. For example, even if the CMake
+      infrastructure is used, if the package <code>.mk</code> file defines its
+      own <code>LIBFOO_CONFIGURE_CMDS</code> variable, it will be used
+      instead of the default CMake one. However, using this method
+      should be restricted to very specific cases. Do not use it in the
+      general case.</li>
+    </ul>

AFAIK, the variable type is only used by CMake GUI so it can use the
most appropriate widget (when manipulating the variables). I didn't
see any use for this in Buildroot so I took it out.

The reason it was included in v1 was that cdrkit.mk had it (which I
based this on) and I did an early release :-) Maybe Thomas (original
cdrkit.mk author) has any comments?

Best regards,
Bj?rn Forsman

No, no specific comment: I'm a CMake newbie, so I didn't know exactly
what the variable type was used for. If it's only for some
CMake-specific GUI, then yes, they are probably useless in Buildroot.

Regards,

Thomas

This does not seem to be sufficient: I don't have <sys/capability.h>
installed system-wide, but it is present in $(HOST_DIR)/usr/include,
but still host-cdrkit doesn't build:

/home/thomas/local/outputs/cmake/build/host-cdrkit-1.1.10/wodim/wodim.c:78:56: error: sys/capability.h: No such file or directory

See the following build log:

CMake Warning (dev) at genisoimage/CMakeLists.txt:52 (ADD_EXECUTABLE):
  Policy CMP0003 should be set before this line.  Add code such as

    if(COMMAND cmake_policy)
      cmake_policy(SET CMP0003 NEW)
    endif(COMMAND cmake_policy)

  as early as possible but after the most recent call to
  cmake_minimum_required or cmake_policy(VERSION).  This warning appears
  because target "devdump" links to some libraries for which the linker must
  search:

    pthread

  and other libraries with known full path:

    /home/thomas/local/outputs/cmake/build/host-cdrkit-1.1.10/wodim/libwodimstuff.a
    /home/thomas/local/outputs/cmake/build/host-cdrkit-1.1.10/libusal/libusal.a
    /home/thomas/local/outputs/cmake/build/host-cdrkit-1.1.10/librols/librols.a
    /home/thomas/local/outputs/cmake/build/host-cdrkit-1.1.10/libunls/libunls.a

  CMake is adding directories in the second list to the linker search path in
  case they are needed to find libraries from the first list (for backwards
  compatibility with CMake 2.4).  Set policy CMP0003 to OLD or NEW to enable
  or disable this behavior explicitly.  Run "cmake --help-policy CMP0003" for
  more information.
This warning is for project developers.  Use -Wno-dev to suppress it.

Ah, I see. CMAKE_REQUIRED_INCLUDES is only used by CHECK_INCLUDE_FILES
(the macro that initially finds sys/capability.h):

-- Looking for include files HAVE_SYS_CAPABILITY_H
-- Looking for include files HAVE_SYS_CAPABILITY_H - found

But CMAKE_REQUIRED_INCLUDES is clearly not used during the build. I
guess I misinterpreted the docs. (Hm... I wonder what purpose
CMAKE_REQUIRED_INCLUDES has then...) I'll replace it with
CMAKE_C_FLAGS. And I'll remove sys/capability.h from my system so I
can spot these things :-)

Thanks for the report.

Best regards,
Bj?rn Forsman

No comments? Is that good or bad? :-)

I plan on disabling ccache for the CMake infrastructure, like Peter
did with cdrkit. Anything else that should be in v3 so it can be
merged?

I'm just back from holidays and would like to give this a test with the
library and application that use CMake I am currently working on. I'll
try to do that tomorrow.

Regards,
