mpi.h is missing even if openmpi exists in ThirdParty-dev

[STK-haan]

Configuration :

• Windows 10
• WSL2
• Ubuntu 22.04
• CUDA 11.1
• RTX3600 (sm_86)
• gcc 9.5

The following is what I did to solve the missing mpi.h error

1. ThirdParty-dev is downloaded from https://github.com/TonkomoLLC/ThirdParty-dev
2. I found that wmake try to access '$HOME/RapidCFD/ThirdParty-dev/openmpi-4.0.2' due to line 403 in '$HOME/RapidCFD/RapidCFD-dev/etc/config/settings.sh
   export FOAM_MPI=openmpi-4.0.2
   But there is only openmpi-2.1.1 so it fails to achieve what intended.
3. I downloaded source of openmpi-4.0.2 from https://www.open-mpi.org/software/ompi/v4.1/ But still, Allwmake shows error for mpi.h is missing
4. I search both openmpi-4.0.2 and openmpi-2.1.1 but there are no file such that mpi.h
5. I googled mpi.h and found following link https://stackoverflow.com/questions/26920083/fatal-error-mpi-h-no-such-file-or-directory-include-mpi-h which suggest I needed to use the MPI compiler wrappers.
6. For now I try to set MPI compiler wrappers during RapidCFD compile, my best guess is modifying RapidCFD-dev/wmake/rules but I have no idea after that point.

I want to know how to remove mpi.h error using ThirdParty-dev
