Hi,

2011/1/15 Bj?rn Forsman <bjorn.forsman@gmail.com>

> 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.

> +# This file implements an infrastructure that eases development of

> +# packages that use CMake as their build system.
> +#
> +# See the Buildroot documentation for details on the usage of this
> +# infrastructure
> +#
> +# In terms of implementation, this CMake infrastructure requires
> +# the .mk file to only specify metadata informations about the
> +# package: name, version, download URL, etc.
> +#
> +# We still allow the package .mk file to override what the different
> +# steps are doing, if needed. For example, if <PKG>_BUILD_CMDS is
> +# already defined, it is used as the list of commands to perform to
> +# build the package, instead of the default CMake behaviour. The
> +# package can also define some post operation hooks.
