How to build MPICH with gfortran-10? - fortran

Question

TL;DR
How to build MPICH with gfortran-10, gcc-10 and g++-10?
Background
I want to build MPICH with grortran-10 so as to be able to use up to date MPI bindings, but I haven't managed to do so. Trying to install MPICH via apt on Ubuntu always uses gfortran 7.5.0 (same version with gcc and g++), even if I have latest version of gfortran installed. Just for clarity, here is my current MPICH and gfortran configuration (installed via apt) :
pavel#pavel:~$ mpiexec --version

With gcc and g++, it's the same as with gfortran in all relevant aspects.

I followed advice VladimirF gave me in the comments, and everthing worked out. This site provided all the necessary guidelines. Only a few minor problems had to be dealth with. Before I could create ./configure file, I was prompted to install some missing autotools, which was simply done using apt. Once ./configure file was ready, I passed in the mostly same configuration that apt originally installed MPICH with (see the long list original question), with 'FC = gfortran-10' 'CC = gcc-10' 'CXX = g++-10' replacing 'FC = gfortran' 'CC = gcc' 'CXX = g++'. Several more prompts had to be dealt with (mostly adding something to configuration or installing missing packages, easily done with Synaptic package manager). After doing all the steps, F08 bindings were succesfully built and work properly. Here is my current MPICH configuration :
