The problem is that this code: https://gitlab.kitware.com/cmake/cmake/blob/v3.9.0/Modules/Platform/Windows-GNU.cmake#L117-127 inserts use of the archiver into the main linking process as a way to work around Windows command-line length limits. Since it is using the archiver as part of linking instead of just for creating a static library, our logic to switch to CMAKE_<LANG>_COMPILER_AR for LTO is not triggering. -Brad -- Powered by www.kitware.com Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Kitware offers various services to support the CMake community.
