   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 informations 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.

  24 # inner-cmake-package -- defines how the configuration, compilation and
  25 # installation of a CMake package should be done, implements a few hooks to
  26 # tune the build process and calls the generic package infrastructure to
  27 # generate the necessary make targets
  28 #
  29 #  argument 1 is the lowercase package name
  30 #  argument 2 is the uppercase package name, including an HOST_ prefix
  31 #             for host packages
  32 #  argument 3 is the uppercase package name, without the HOST_ prefix
  33 #             for host packages
  34 #  argument 4 is the package directory prefix
  35 #  argument 5 is the type (target or host)
