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: ${CMAKE_REMOVE_MODULES:=yes}
67CMAKE_REMOVE_MODULES="${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)
