13 # @BLURB: common ebuild functions for cmake-based packages
14 # @DESCRIPTION:
15 # The cmake-utils eclass is base.eclass(5) wrapper that makes creating ebuilds for
16 # cmake-based packages much easier.
17 # It provides all inherited features (DOCS, HTML_DOCS, PATCHES) along with out-of-source
18 # builds (default), in-source builds and an implementation of the well-known use_enable
19 # and use_with functions for CMake.
20
21 # @ECLASS-VARIABLE: WANT_CMAKE
22 # @DESCRIPTION:
23 # Specify if cmake-utils eclass should depend on cmake optionaly or not.
24 # This is usefull when only part of aplication is using cmake build system.
25 # Valid values are: always [default], optional (where the value is the useflag
26 # used for optionality)
27 WANT_CMAKE="${WANT_CMAKE:-always}"

29 # @ECLASS-VARIABLE: CMAKE_MIN_VERSION

32 CMAKE_MIN_VERSION="${CMAKE_MIN_VERSION:-2.8.4}"
33
34 # @ECLASS-VARIABLE: CMAKE_REMOVE_MODULES_LIST
35 # @DESCRIPTION:
36 # Space-separated list of CMake modules that will be removed in $S during src_prepare,
37 # in order to force packages to use the system version.

131 # If about to be set - needs to be set before invoking cmake-utils_src_configure.

145 # By default it uses ${S}.
