 # CMake package infrastructure
 #
 # This file implements an infrastructure that eases development of
 # package .mk files for CMake packages. It should be used for all
 # 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 information 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.
