# CMake is a particular package:
# * CMake can be built using the generic infrastructure or the cmake one.
#   Since Buildroot has no requirement regarding the host system cmake
#   program presence, it uses the generic infrastructure to build the
#   host-cmake package, then the (target-)cmake package can be built
#   using the cmake infrastructure;
# * CMake bundles its dependencies within its sources. This is the
#   reason why the host-cmake package has no dependencies:, whereas
#   the (target-)cmake package has a lot of dependencies, using only
#   the system-wide libraries instead of rebuilding and statically
#   linking with the ones bundled into the CMake sources.
