CMakeDetermineCompilerABI: Extract lib arch from implicit object file paths (!5984) · Merge requests · CMake / CMake

Robert Maynard requested to merge robertmaynard/cmake:correct_CMAKE_LIBRARY_ARCHITECTURE_regression into master Apr 05, 2021

The change in !5773 (merged) caused CMAKE_LIBRARY_ARCHITECTURE to be populated on non-multiarch platforms if their compilers happen to use $arch/$version library directories. Revert the use of versioned library paths. Use another solution for NVHPC.

The NVHPC compiler does not have any implicit link directories that can be used to detect CMAKE_LIBRARY_ARCHITECTURE, but it does have implicit object files. Extract implicit object file paths from link lines and check them for the CMAKE_LIBRARY_ARCHITECTURE pattern.

Fixes: #22024 (closed)
Backport: release
Topic-rename: nvhpc-lib-arch
