# @BLURB: common ebuild functions for cmake-based packages
# @DESCRIPTION:
# The cmake 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 function for CMake.

_CMAKE_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.
: ${ BUILD_DIR : = ${ WORKDIR } / ${ P } _build }
# @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_src_configure.
# You usually 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
# @DEFAULT_UNSET
# @DESCRIPTION:
# Set to enable in-source build.
# @ECLASS-VARIABLE: CMAKE_MAKEFILE_GENERATOR
# @DEFAULT_UNSET
# @DESCRIPTION:
# Specify a makefile generator to be used by cmake.
# At this point only "emake" and "ninja" are supported.
# The default is set to "ninja".
: ${ CMAKE_MAKEFILE_GENERATOR : =ninja }
# @ECLASS-VARIABLE: CMAKE_REMOVE_MODULES_LIST
# @DESCRIPTION:
# Array of CMake modules that will be removed in $S during src_prepare,
# in order to force packages to use the system version.
# Set to "none" to disable removing modules entirely.
: ${ 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 : =yes }
# @ECLASS-VARIABLE: CMAKE_EXTRA_CACHE_FILE
# @DEFAULT_UNSET
# @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.
# @ECLASS-VARIABLE: CMAKE_QA_SRC_DIR_READONLY
# @DEFAULT_UNSET
# @DESCRIPTION:
# After running cmake_src_prepare, sets ${S} to read-only. This is
# a user flag and should under _no circumstances_ be set in the ebuild.
# Helps in improving QA of build systems that write to source tree.
