update the cmake build system to work when included in a cmake project

[simonpintarelli]

• New tiled-mm api
• Use findBlas routine adapted from cp2k (add flexiblas, armpl) to detect blas implementation
• Support both in tree and out of tree costa and tiled-mm (submodules)
• Fix cosmaConfig.cmake to work properly when included in an other cmake project
• semiprof and cxxopts are treated as external dependencies
• removed the SCALAPACK_BLAS option
• Force costa and tiled-mm installation when costa and tiled-mm are included as submodule

can we merge ?

Looks good to me. Just one thing: do we want to allow COSMA_BLAS_VENDOR_LIST to be NONE? I guess this is required. Alternatively, we can add some basic implementation for local gemm calls, but there is probably no need for it.

I use OFF instead of NONE after following both simon and your suggestion.

It is off by default and an error message will show up if COSMA_BLAS=OFF so the user is warmed. It means that this parameter should be explicitly set during compilation time. It is also the old behavior because we did not want to complicate the spack recipe too much between versions.

If COSMA_BLAS=CUDA,ROCM then the BLAS implementation is the scalapack one if COSMA_SCALAPACK=MKL,CRAY_LIBSCI,CUSTOM.

if you agree I will create a tagged version of COSMA as well and create a PR for spack

Sure, once you believe it's ready, feel free to merge it and make a new release.

For the release, just pay attention to the following:

• Before creating a release, make sure to modify the version in cmake, because there is a github action which checks if the tag is the same as the version inside cmake.
• To include submodules in the release files, I had to manually attach .tar.gz and .zip as assets to the release.
