# CMAKE_ENV		- Environment passed to cmake.
#				Default: ${CONFIGURE_ENV}
# CMAKE_ARGS		- Arguments passed to cmake
#				Default: see below
# CMAKE_USE_PTHREAD	- Instruct cmake to use pthreads when compiling/linking
#				Default: not set
# CMAKE_BUILD_TYPE	- Type of build (cmake predefined build types).
#				Projects may have their own build profiles.
#				CMake supports the following types: Debug,
#				Release, RelWithDebInfo and MinSizeRel.
#				Debug and Release profiles respect system
#				CFLAGS, RelWithDebInfo and MinSizeRel will set
#				CFLAGS to "-O2 -g" and "-Os -DNDEBUG".
#				Default: Release, if WITH_DEBUG is not set,
#				Debug otherwise
# CMAKE_VERBOSE		- Verbose build
#				Default: not set
# CMAKE_OUTSOURCE	- Instruct to perform an out-of-source build
# 				Default: not set
# CMAKE_SOURCE_PATH	- Path to sourcedir for cmake
#				Default: ${WRKSRC}
# CMAKE_INSTALL_PREFIX	- prefix for cmake to use for installation.
#				Default: ${PREFIX}
