Missing MPI files when Installing Hypre on Windows with CMake for Visual Studio

[tmpnemophd]

Hello,

I am trying to install Hypre (ver. 2.11.2) on my Windows machine using CMake (ver. 3.14.0), but I am having some trouble due to missing mpi.h files. I was wondering if I could receive any help resolving this issue. I am new to Hypre and I am just trying to get any example code to run.

When I build the binaries (configured for Visual Studio 2011; x64) on CMake following the installation instruction, I receive the following messages:

---

The C compiler identification is MSVC 17.0.50727.1
The CXX compiler identification is MSVC 17.0.50727.1

Could NOT find MPI (missing: MPI_C_FOUND MPI_CXX_FOUND)
Configuring done

Then, as instructed, I generate the build files.

When I open up Visual Studio and try to build the "ALL_BUILD" target, I run into 395 errors, all of which say the following line:
"error C1083: Cannot open include file: 'mpi.h': No such file or directory"
The associated File is "HYPRE_utilities.h" and Line = 25.

Based on the error messages I get, both on CMake and Visual Studio, I think this issue has to do with MPI. Is there any way to bypass MPI? My ultimate intention is to utilize OpenMP-enabled Linear-Algebraic System Interface in Fortran, and I do NOT need MPI for my applications.

Thank you.

Hello, Yes, you can turn off MPI by turning the CMake configuration option HYPRE_SEQUENTIAL to ON. Hope this helps!
