# 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.
