Regarding the detection of MPI with FindMPI, I failed to detect the MPI compiler using `MPI_CXX_COMPILER_FLAGS`. But using the normal Fujitsu compiler binary (not the wrapper) and setting `MPI_CXX_COMPILER`, I can detect it.</div>

The problem is now that it does not detect the STL anymore at compiling time: "error: namespace "std" has no member "array"" (note that I used to build the project with a hand made Makefile, so the source code is valid). I checked the `include` directory of
the compiler and it contains the Array header, though. In other warnings, I clearly see that this `include` directory is used. What is wrong here?<br>

I would look at the FindMPI docs on locating the correct mpi compiler:<br>
<a href="https://cmake.org/cmake/help/v3.14/module/FindMPI.html#variables-for-locating-mpi">https://cmake.org/cmake/help/v3.14/module/FindMPI.html#variables-for-locating-mpi</a><br>
. It looks like what you will need to specify is<br>
MPI_<lang>_COMPILER_FLAGS<br>

only needs one argument to enable MPI features. I tried with some exotic-named GCC compilers at my lab (which are MPI wrappers as well) and it could detect MPI with no problem. Where should I start?<br>
