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

24 # @ECLASS-VARIABLE: BUILD_DIR
25 # @DESCRIPTION:
26 # Build directory where all cmake processed files should be generated.
27 # For in-source build it's fixed to ${CMAKE_USE_DIR}.
28 # For out-of-source build it can be overridden, by default it uses
29 # ${WORKDIR}/${P}_build.
30 #
31 # This variable has been called CMAKE_BUILD_DIR formerly.
32 # It is set under that name for compatibility.
33
34 # @ECLASS-VARIABLE: CMAKE_BINARY
35 # @DESCRIPTION:
36 # Eclass can use different cmake binary than the one provided in by system.
37 : ${CMAKE_BINARY:=cmake}
38
39 # @ECLASS-VARIABLE: CMAKE_BUILD_TYPE
40 # @DESCRIPTION:
41 # Set to override default CMAKE_BUILD_TYPE. Only useful for packages
42 # known to make use of "if (CMAKE_BUILD_TYPE MATCHES xxx)".
43 # If about to be set - needs to be set before invoking cmake-utils_src_configure.
44 # You usualy do *NOT* want nor need to set it as it pulls CMake default build-type
45 # specific compiler flags overriding make.conf.
46 : ${CMAKE_BUILD_TYPE:=Gentoo}
47
48 # @ECLASS-VARIABLE: CMAKE_IN_SOURCE_BUILD
49 # @DESCRIPTION:
50 # Set to enable in-source build.
51
52 # @ECLASS-VARIABLE: CMAKE_MAKEFILE_GENERATOR
53 # @DESCRIPTION:
54 # Specify a makefile generator to be used by cmake.
55 # At this point only "emake" and "ninja" are supported.
56 : ${CMAKE_MAKEFILE_GENERATOR:=emake}
57
58 # @ECLASS-VARIABLE: CMAKE_MIN_VERSION
59 # @DESCRIPTION:
60 # Specify the minimum required CMake version.
61 : ${CMAKE_MIN_VERSION:=2.8.12}
62
63 # @ECLASS-VARIABLE: CMAKE_REMOVE_MODULES
64 # @DESCRIPTION:
65 # Do we want to remove anything? yes or whatever else for no
66 : ${CMAKE_REMOVE_MODULES:=yes}
67 CMAKE_REMOVE_MODULES="${CMAKE_REMOVE_MODULES:-yes}"
68
69 # @ECLASS-VARIABLE: CMAKE_REMOVE_MODULES_LIST
70 # @DESCRIPTION:
71 # Space-separated list of CMake modules that will be removed in $S during src_prepare,
72 # in order to force packages to use the system version.
73 : ${CMAKE_REMOVE_MODULES_LIST:=FindBLAS FindLAPACK}
74
75 # @ECLASS-VARIABLE: CMAKE_USE_DIR
76 # @DESCRIPTION:
77 # Sets the directory where we are working with cmake.
78 # For example when application uses autotools and only one
79 # plugin needs to be done by cmake.
80 # By default it uses ${S}.
81
82 # @ECLASS-VARIABLE: CMAKE_VERBOSE
83 # @DESCRIPTION:
84 # Set to OFF to disable verbose messages during compilation
85 : ${CMAKE_VERBOSE:=ON}
86
87 # @ECLASS-VARIABLE: CMAKE_WARN_UNUSED_CLI
88 # @DESCRIPTION:
89 # Warn about variables that are declared on the command line
90 # but not used. Might give false-positives.
91 # "no" to disable (default) or anything else to enable.
92 : ${CMAKE_WARN_UNUSED_CLI:=no}
93
94 # @ECLASS-VARIABLE: PREFIX
95 # @DESCRIPTION:
96 # Eclass respects PREFIX variable, though it's not recommended way to set
97 # install/lib/bin prefixes.
98 # Use -DCMAKE_INSTALL_PREFIX=... CMake variable instead.
99 : ${PREFIX:=/usr}
100
101 # @ECLASS-VARIABLE: WANT_CMAKE
102 # @DESCRIPTION:
103 # Specify if cmake-utils eclass should depend on cmake optionally or not.
104 # This is useful when only part of application is using cmake build system.
105 # Valid values are: always [default], optional (where the value is the useflag
106 # used for optionality)
107 : ${WANT_CMAKE:=always}
108
109 # @ECLASS-VARIABLE: CMAKE_EXTRA_CACHE_FILE
110 # @DESCRIPTION:
111 # Specifies an extra cache file to pass to cmake. This is the analog of EXTRA_ECONF
112 # for econf and is needed to pass TRY_RUN results when cross-compiling.
113 # Should be set by user in a per-package basis in /etc/portage/package.env.
