# @BLURB: cmake-utils wrapper for multilib builds
# @DESCRIPTION:
# The cmake-multilib.eclass provides a glue between cmake-utils.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-utils 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-utils
# phase rather than 'default'.
# EAPI=5 is required for meaningful MULTILIB_USEDEP.
