Summary0011260: Add GLOBAL FIND_LIBRARY_USE_LIB32_PATHS property, whose behavior is like FIND_LIBRARY_USE_LIB64_PATHS
DescriptionCMake has a global property called FIND_LIBRARY_USE_LIB64_PATHS which automatically adds "lib64" to various search-paths when a 64-bit build is detected. This property affects the search paths for at least:
FIND_LIBRARY()
FIND_PACKAGE(<MODULE_NAME> NO_MODULE)

Merely having a FIND_LIBRARY_USE_LIB64_PATHS property and thus support for /usr/lib64 and /lib64 ignores the push for multilib support which in enough cases uses the /lib32 and /usr/lib32 directories for 32-bit libraries.

CMake Warning at CMakeLists.txt:1 (FIND_PACKAGE):
  Could not find a configuration file for package Automoc4.

  Set Automoc4_DIR to the directory containing a CMake configuration file for
  Automoc4. The file will have one of the following names:

    Automoc4Config.cmake
    automoc4-config.cmake

cmake-FIND_LIBRARY_USE_LIB32_PATHS-property-multilib-r1.patch: This version actually sets the harmless FIND_LIBRARY_USE_LIB32_PATHS option to be enabled by default. Otherwise, it should be the exact same as the previously posted patch.

Is there any progress being made on merging this patch or an alternate solution. It sucks having to work around this CMake deficiency in every project that needs 32-bit libs.

Just wanted to note that this is still an issue for switching between hunting for 32 and 64 bit libraries - are there any plans to fix it?
