# @SUPPORTED_EAPIS: 7 8
# @PROVIDES: cmake multilib-minimal
# @BLURB: cmake wrapper for multilib builds
# @DESCRIPTION:
# The cmake-multilib.eclass provides a glue between cmake.eclass(5)
# and multilib-minimal.eclass(5), aiming to provide a convenient way
# to build packages using cmake for multiple ABIs.
#
# Inheriting this eclass sets IUSE and exports default multilib_src_*()
# sub-phases that call cmake phase functions for each ABI enabled.
# The multilib_src_*() functions can be defined in ebuild just like
# in multilib-minimal, yet they ought to call appropriate cmake
# phase rather than 'default'.

# @ECLASS_VARIABLE: CMAKE_ECLASS
# @DEPRECATED: none
# @DESCRIPTION:
# Only "cmake" is supported.
