close #209

Hi @amontoison, can you rebase and change: if (NOT CMAKE_CXX_COMPILER_ID STREQUAL "Clang") to if (NOT CMAKE_CXX_COMPILER_ID STREQUAL "Clang" AND NOT CMAKE_SYSTEM_PROCESSOR STREQUAL "arm64") in the CMakeLists?

Latest progress:

build-windows.yml
- passed the right path to the HiGHS directory, HiGHS is now found but not properly linked. Had to drop x86 builds.
- the blas and lapack libraries are found but not properly linked. Perhaps a conflict between MinGW32 and MinGW64?
build-macos.yml
- macos-latest is only available for arm64. Kept only the two configurations (macos-latest, arm64) and (macos-13, x64).
- passed the right path to the HiGHS directory, HiGHS is now found but not properly linked.
- still undefined symbols such as __mcount for arm64. It looks like it comes from incorrect flags -pg in Debug mode. The fix for Clang was merged in main in https://github.com/cvanaret/Uno/commit/57a5255bbd3627b340f512cf27e128a626036f02.

So, we can link HiGHS without errors on macOS, provided we compile with Clang. This also assumes we ditch BQPD and MUMPS so that we don't have to bring in a Fortran compiler.
