| # @BLURB: common ebuild functions for cmake-based packages |
| # @DESCRIPTION: |
| # The cmake-utils eclass makes creating ebuilds for cmake-based packages much easier. |
| # It provides all inherited features (DOCS, HTML_DOCS, PATCHES) along with out-of-source |
| # builds (default), in-source builds and an implementation of the well-known use_enable |
| # and use_with functions for CMake. |
| |

| |
| # @ECLASS-VARIABLE: BUILD_DIR |
| # @DESCRIPTION: |
| # Build directory where all cmake processed files should be generated. |
| # For in-source build it's fixed to ${CMAKE_USE_DIR}. |
| # For out-of-source build it can be overridden, by default it uses |
| # ${WORKDIR}/${P}_build. |
| # |
| # This variable has been called CMAKE_BUILD_DIR formerly. |
| # It is set under that name for compatibility. |
| |
| # @ECLASS-VARIABLE: CMAKE_BINARY |
| # @DESCRIPTION: |
| # Eclass can use different cmake binary than the one provided in by system. |
| : ${CMAKE_BINARY:=cmake} |
| |
| # @ECLASS-VARIABLE: CMAKE_BUILD_TYPE |
| # @DESCRIPTION: |
| # Set to override default CMAKE_BUILD_TYPE. Only useful for packages |
| # known to make use of "if (CMAKE_BUILD_TYPE MATCHES xxx)". |
| # If about to be set - needs to be set before invoking cmake-utils_src_configure. |
| # You usualy do *NOT* want nor need to set it as it pulls CMake default build-type |
| # specific compiler flags overriding make.conf. |
| : ${CMAKE_BUILD_TYPE:=Gentoo} |
| |
| # @ECLASS-VARIABLE: CMAKE_IN_SOURCE_BUILD |
| # @DESCRIPTION: |
| # Set to enable in-source build. |
| |
| # @ECLASS-VARIABLE: CMAKE_MAKEFILE_GENERATOR |
| # @DESCRIPTION: |
| # Specify a makefile generator to be used by cmake. |
| # At this point only "emake" and "ninja" are supported. |
| : ${CMAKE_MAKEFILE_GENERATOR:=emake} |
| |
| # @ECLASS-VARIABLE: CMAKE_MIN_VERSION |
| # @DESCRIPTION: |
| # Specify the minimum required CMake version. |
| : ${CMAKE_MIN_VERSION:=2.8.12} |
| |
| # @ECLASS-VARIABLE: CMAKE_REMOVE_MODULES |
| # @DESCRIPTION: |
| # Do we want to remove anything? yes or whatever else for no |
| : ${CMAKE_REMOVE_MODULES:=yes} |
| |
| # @ECLASS-VARIABLE: CMAKE_REMOVE_MODULES_LIST |
| # @DESCRIPTION: |
| # Space-separated list of CMake modules that will be removed in $S during src_prepare, |
| # in order to force packages to use the system version. |
| : ${CMAKE_REMOVE_MODULES_LIST:=FindBLAS FindLAPACK} |
| |
| # @ECLASS-VARIABLE: CMAKE_USE_DIR |
| # @DESCRIPTION: |
| # Sets the directory where we are working with cmake. |
| # For example when application uses autotools and only one |
| # plugin needs to be done by cmake. |
| # By default it uses ${S}. |
| |
| # @ECLASS-VARIABLE: CMAKE_VERBOSE |
| # @DESCRIPTION: |
| # Set to OFF to disable verbose messages during compilation |
| : ${CMAKE_VERBOSE:=ON} |
| |
| # @ECLASS-VARIABLE: CMAKE_WARN_UNUSED_CLI |
| # @DESCRIPTION: |
| # Warn about variables that are declared on the command line |
| # but not used. Might give false-positives. |
| # "no" to disable (default) or anything else to enable. |
| : ${CMAKE_WARN_UNUSED_CLI:=no} |
| |
| # @ECLASS-VARIABLE: PREFIX |
| # @DESCRIPTION: |
| # Eclass respects PREFIX variable, though it's not recommended way to set |
| # install/lib/bin prefixes. |
| # Use -DCMAKE_INSTALL_PREFIX=... CMake variable instead. |
| : ${PREFIX:=/usr} |
| |
| # @ECLASS-VARIABLE: WANT_CMAKE |
| # @DESCRIPTION: |
| # Specify if cmake-utils eclass should depend on cmake optionally or not. |
| # This is useful when only part of application is using cmake build system. |
| # Valid values are: always [default], optional (where the value is the useflag |
| # used for optionality) |
| # |
| # This is banned in EAPI 6 and later. |
| : ${WANT_CMAKE:=always} |
| |
| # @ECLASS-VARIABLE: CMAKE_EXTRA_CACHE_FILE |
| # @DESCRIPTION: |
| # Specifies an extra cache file to pass to cmake. This is the analog of EXTRA_ECONF |
| # for econf and is needed to pass TRY_RUN results when cross-compiling. |
| # Should be set by user in a per-package basis in /etc/portage/package.env. |
