# - Multiarch support in object code library directories
#
# This module sets the following variable
# CMAKE_INSTALL_LIBDIR to lib, lib64 or lib/x86_64-linux-gnu
# depending on the platform; use this path
# for platform-specific binaries.
#
# CMAKE_INSTALL_LIBDIR_NOARCH to lib or lib64 depending on the platform;
# use this path for architecture-independent
# files.
#
# Note that it will override the results of GNUInstallDirs if included after
# that module.
# Fedora uses lib64/ for 64-bit systems, Debian uses lib/x86_64-linux-gnu;
# Fedora put module files in lib64/ too, but Debian uses lib/ for that
