- # 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 informations 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.

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