Question: failed installation on a x86_64-redhat-linux-gnu notebook running Fedora 42

Hi there.

I have a notebook x86_64-redhat-linux-gnu running Fedora 42 and intend to install Opencoarrays with a beta installation of mpich (the last one). So far I have tried two ways:

1. Using the suggested in the "Developer Build and Install" section.

2. Using the install.sh script with:

./install.sh --prefix-root ${PREFIX} --num-threads 4 --with-fortran mpifort --with-cxx mpic++ --with-c mpicc --with-mpi /usr/beta/mpich

e.g. see the attached error.

error.log

At the end of this log file, the error is:

-- Performing Test MPI_C_COMPILES - Failed
CMake Error at CMakeLists.txt:446 (message):
MPI_C is missing! Try setting MPI_C_COMPILER to the appropriate C compiler
wrapper script and reconfigure. i.e., cmake -DMPI_C_COMPILER=/path/to/mpicc .. or set it by editing the cache using
cmake-gui or ccmake.

Please, in any option, where and how to define precisely the values of the variables that are missing? (Please note: I am a new CMake user ...).

Thank you in advance.
Best regards.

Jorge D'Elia.
