# 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)
