# @BLURB: common ebuild functions for cmake-based packages
# @DESCRIPTION:
# The cmake-utils eclass is base.eclass(5) wrapper that 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.

# @ECLASS-VARIABLE: WANT_CMAKE
# @DESCRIPTION:
# Specify if cmake-utils eclass should depend on cmake optionaly or not.
# This is usefull when only part of aplication is using cmake build system.
# Valid values are: always [default], optional (where the value is the useflag
# used for optionality)
WANT_CMAKE="${WANT_CMAKE:-always}"

# @ECLASS-VARIABLE: CMAKE_MIN_VERSION
# @DESCRIPTION:
# Specify the minimum required CMake version.  Default is 2.8.4
CMAKE_MIN_VERSION="${CMAKE_MIN_VERSION:-2.8.4}"

# @ECLASS-VARIABLE: CMAKE_REMOVE_MODULES_LIST
# @DESCRIPTION:
# Space-separated list of CMake modules that will be removed in $S during src_prepare,
# in order to force packages to use the system version.
CMAKE_REMOVE_MODULES_LIST="${CMAKE_REMOVE_MODULES_LIST:-FindBLAS FindLAPACK}"

# @ECLASS-VARIABLE: CMAKE_REMOVE_MODULES
# @DESCRIPTION:
# Do we want to remove anything? yes or whatever else for no
CMAKE_REMOVE_MODULES="${CMAKE_REMOVE_MODULES:-yes}"

# @ECLASS-VARIABLE: CMAKE_MAKEFILE_GENERATOR
# @DESCRIPTION:
# Specify a makefile generator to be used by cmake. At this point only "make"
# and "ninja" is supported.
CMAKE_MAKEFILE_GENERATOR="${CMAKE_MAKEFILE_GENERATOR:-make}"

# ${WORKDIR}/${P}_build.

# @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

# For example when application uses autotools and only one

# @ECLASS-VARIABLE: CMAKE_VERBOSE
# @DESCRIPTION:
# Set to OFF to disable verbose messages during compilation
