We want to add Catalyst2 API - DOCS, Catalyst2 API - Source Code to be used as the In-Situ Framework.
In order to link against Catalyst 2 we need to have the MPI_C compiler available.
Otherwise we receive an error such as:

-- Adding index test found in alpine
CMake Error at /p/software/juwels/stages/2023/software/CMake/3.23.1-GCCcore-11.3.0/share/cmake-3.23/Modules/FindPackageHandleStandardArgs.cmake:230 (message):
  Could NOT find MPI (missing: MPI_C_FOUND C)

      Reason given by package: MPI component 'C' was requested, but language C is not enabled.

Without specifying this option the C compilers are not available.

However it is still a work in progress, and we are still facing some issues after having the library linked, so this might be changed.
