I used above CMake setup (albeit with the pre-monorepo separate git repositories) and the four test failures still reproduced. Are you willing to share your CMakeCache.txt so that I might diff your setup with mine?
Also, given that two of the test failures are Intel specific (the mxcsr register write failures), what class of hardware do you use? My workstation is Skylake-SP based, if it matters.
