################################################################################ # 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 _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) ################################################################################ define inner-cmake-package $(2)_CONF_ENV ?= $(2)_CONF_OPT ?= $(2)_MAKE ?= $(MAKE) $(2)_MAKE_ENV ?= $(2)_MAKE_OPT ?= $(2)_INSTALL_HOST_OPT ?= install $(2)_INSTALL_STAGING_OPT ?= DESTDIR=$$(STAGING_DIR) install $(2)_INSTALL_TARGET_OPT ?= DESTDIR=$$(TARGET_DIR) install $(2)_CLEAN_OPT ?= clean $(2)_SRCDIR = $$($(2)_DIR)/$($(2)_SUBDIR) $(2)_BUILDDIR = $$($(2)_SRCDIR) # # Configure step.
