[PATCH 1/5] kernel-shark: Start using libtracecmd

[Yordan Karadzhov (VMware)]

libtracecmd is now a stand-alone libraries, similar to libtraceevent
and libtracefs. Start building and linking KernelShark against this
independent library.

[PATCH 3/5] kernel-shark: Change default libraries install location

[Yordan Karadzhov (VMware)]

The default installation path for the KernelShark libraries changes from
/usr/local/lib/kernelshark/ to /usr/local/lib64 (or /usr/local/lib on
32 but systems). This is done in order to be consistent with the install
locations of libtraceevent, libtracefs and libtracecmd.

[PATCH 4/5] kernel-shark: Split the installation in two components

[Yordan Karadzhov (VMware)]

The user can choose to install only the KernelShark GUI via
"install_gui.sh". It is also possible to install the library headers
and this can be done via "install_libkshark-devel.sh".

The changes implemented in this patch are inspired by the talk
"Deep CMake For Library Authors" presented at CppCon 2019 by Craig Scott.

I applied the series. But is there a way to install in a specific directory
and not in the system directories? (I didn't watch the talk).

For example, I can do:

 $ mkdir /tmp/install
 $ make DESTDIR=/tmp/install/ install

for libtraceveent, libtracefs and trace-cmd / libtracecmd and it will
install into /tmp/install/... just like it would have installed in /. The
big difference is, I don't need to be root to run that command.

Then what I can do is:

 $ cd /tmp/install
 $ tar -cvjf ../package.tar.bz2 .
 $ scp ../package.tar.bz2 root@somebox:/tmp
 $ ssh root@somebox
 # cd /
 # tar -xvjf /tmp/package.tar.bz2

And that would have installed the package on to the machine "somebox".

Yes, we have a similar functionality since the very beginning of KS 1.0 
and it is not been changed here. You can specify the install destination 
using a cmake command line argument like this:

cmake -D_INSTALL_PREFIX=/tmp/install/ ..

All this is documented in the README file. The only difference is that 
in your case you provide the destination at the very end when you do 
"make install", while here it has to be done at the very beginning when 
you call cmake.

Note that the two new helper scripts (install_gui.sh and 
install_libkshark-devel.sh) can be used instead of "sudo make install" 
but this is needed only if you want to split the installation. A normal 
"make install" will just install everything.

However, you are right that it is probably better if we remove the sudo 
from the two helper scripts.

Thanks!
Yordan
