# @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.
if [[ -z ${_CMAKE_UTILS_ECLASS} ]]; then
_CMAKE_UTILS_ECLASS=1
# @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
: ${CMAKE_REMOVE_MODULES:=yes}
CMAKE_REMOVE_MODULES="${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)
: ${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.
