# @BLURB: cmake-utils wrapper for multilib builds
# @DESCRIPTION:
# The cmake-multilib.eclass is a cmake-utils.eclass(5) wrapper
# introducing support for building for more than one ABI (multilib).
#
# Inheriting this eclass sets IUSE and exports cmake-utils phase
# function wrappers which build the package for each supported ABI
# if the appropriate flag is enabled.
#
# Note that the multilib support requires out-of-source builds to be
# enabled. Thus, it is impossible to use CMAKE_IN_SOURCE_BUILD with
# it.

# EAPI=5 is required for meaningful MULTILIB_USEDEP.
