   2 # CMake package infrastructure
   3 #
   4 # This file implements an infrastructure that eases development of
   5 # package .mk files for CMake packages. It should be used for all
   6 # packages that use CMake as their build system.
   7 #
   8 # See the Buildroot documentation for details on the usage of this
   9 # infrastructure
  10 #
  11 # In terms of implementation, this CMake infrastructure requires
  12 # the .mk file to only specify metadata information about the
  13 # package: name, version, download URL, etc.
  14 #
  15 # We still allow the package .mk file to override what the different
  16 # steps are doing, if needed. For example, if <PKG>_BUILD_CMDS is
  17 # already defined, it is used as the list of commands to perform to
  18 # build the package, instead of the default CMake behaviour. The
  19 # package can also define some post operation hooks.
