Following the instructions from my second link in my original post, these are the compiler versions I get

$ sudo yum install devtoolset-9
$ scl enable devtoolset-7 bash
$ module load mpi/openmpi-x86_64
$ export CC=mpicc; export CXX=mpicxx; export FC=mpif90; export FF=mpif77

Gives me the following compiler versions:

$ gcc --version
gcc (GCC) 9.3.1 20200408 (Red Hat 9.3.1-2)
...

$ mpicc --version
gcc (GCC) 9.3.1 20200408 (Red Hat 9.3.1-2)
...

$ mpicxx --version
g++ (GCC) 9.3.1 20200408 (Red Hat 9.3.1-2)
...

$ mpif90 --version
GNU Fortran (GCC) 9.3.1 20200408 (Red Hat 9.3.1-2)
...

$ mpif77 --version
GNU Fortran (GCC) 9.3.1 20200408 (Red Hat 9.3.1-2)
...

$ mpifort --version
GNU Fortran (GCC) 9.3.1 20200408 (Red Hat 9.3.1-2)
...

Ah, nice idea. I always compile my own gcc+mpi compiler for centos to keep the build chain in track over years.

Your ideas seems feasible, to my knowlegde, the scl packages and devtoolsets were only available on rhel.
Does this include fitting mpi (openmpi or mpich) compilers for those gcc compilers as well?

Do you like to setup a pull request for the notes and your cmake?

For cmake: add the cmake package in this file
