Summary0015994: CMake support for the Linux x86-64 32-bit ABI (x32-abi)
DescriptionCurrently CMake assumes library files can be located in ${CMAKE_INSTALL_PREFIX}/lib{64}, or otherwise on the system in /lib{64}, /usr/lib{64} etc. This isn't the case with x32-abi, where library directories are postfixed with x32, for example: ${CMAKE_INSTALL_PREFIX}/libx32

This results in CMake modules being unable to locate their resources, including failure during the configuration of CMake itself after initial bootstrap if CMAKE_INSTALL_PREFIX and individual *_DIR=/usr/libx32/cmake/* variables aren't manually provided.
Steps To ReproduceBuild CMake from source on x32. Attempt to build projects with CMake.
Additional InformationThe attached patch is from pld-linux, a similar patch also exists for Gentoo Linux. This gives CMake the extra knowledge necessary to successfully locate the library paths on x32-abi.

Perhaps, in the future a centralised CMake facility could provide system library paths?
TagsNo tags attached.

The patch appears to be hard-coded for use on packaging CMake for the x32 architecture. Several places replace "lib/" with "libx32/" unconditionally. Therefore additional work will be needed to make such a change upstreamable. It may be easier to do this in pieces.

Such discussion would be better held on the developer list:

Re 0015994:0040814: Yes, thanks. If anyone wants to move the issue forward please pick up the patch attached to 0011260, rebase/revise as needed on 'master', and bring it to the dev mailing list linked in 0015994:0040584.

Is it really a duplicate? The linked bug is talking about lib32, whereas the issue here is libx32. Those are distinct paths.
