Restoring compiler autodetection will solve this warning as well, see this series: https://review.trustedfirmware.org/q/topic:%22build_autodetect%22

This would also be the recommended way in modern CMake to avoid compiler forcing for cross-compilation toolchains, see https://cmake.org/cmake/help/v3.28/module/CMakeForceCompiler.html

Hi Brian,

I have noticed that warning in the past and I believe at that time it was fixed by adding LANGUAGES property explicit in the project() call in the root Mbed TLS CMakelists.txt, just before GnuInstallDirs is included. But for some reason this has come back and I have not been able to pinpoint the root cause. It is safe to say at this point that the warning is benign and has no impact whatsoever on the build. I will try to spend some more time on this if time permits.

Thanks, Antonio ________________________________ From: Quach, Brian via TF-M tf-m@lists.trustedfirmware.org Sent: Friday, February 16, 2024 15:39 To: tf-m@lists.trustedfirmware.org tf-m@lists.trustedfirmware.org Subject: [TF-M] Unable to determine default CMAKE_INSTALL_LIBDIR directory

Hi,

I’m seeing this warning when running cmake from a conan pkg: `/home/brian/.conan/data/cmake/3.21.3-0/library-msp/ga/package/be241241e9d4718e5bab4eb33935bbb69606bb0c/bin/cmake -S . -B build -DTFM_PLATFORM=arm/mps2/an521`. Does anyone know how to fix it? I see the language is set by `project("Trusted Firmware M" VERSION ${TFM_VERSION} LANGUAGES C CXX ASM)`.

Per-partition files done:

This warning is for project developers. Use -Wno-dev to suppress it.
