Teach find_(library|package) about Linux multiarch (#12037)
Implement support for multiarch as specified here: http://wiki.debian.org/Multiarch https://wiki.ubuntu.com/MultiarchSpec Detect the <arch> part of <prefix>/lib/<arch> from the implicit library search path from each compiler to set CMAKE_<lang>_LIBRARY_ARCHITECTURE. Define CMAKE_LIBRARY_ARCHITECTURE using one of these values (they should all be the same). Teach the find_library and find_package commands to search <prefix>/lib/<arch> whenever they would search <prefix>/lib.
