# 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)
