Since I haven't worked with MPI, I don't think I can help much. Try
using the message command to dump variable contents<br>
e.g. message(STATUS "CMAKE_C_FLAGS = ${CMAKE_C_FLAGS}")<br>
You may need to add includes explicitly with the
"include_directories" (or similar) command. Hopefully some else
using MPI can jump in.<br>

<div>Hi,<br>
<br>
</div>
I am using cmake to create Makefile. I am using
MPI in my project but I only want to use the C
(mpicc) not C++ (mpicxx) following is the
CMakeLists.txt:<br>
<div>
<div><br>
</div>
<div>I have tested it but on some platforms it
seems that it only detects the C++ mpi
(mpicxx) and uses its libraries. This creates
errors (mpi.h not found) as the project only
needs C (mpicc and its libraries).<br>
<br>
</div>
<div>So how to force cmake to only search for C
(mpicc) and use its libraries (the mpi.h not
mpicxx.h).<br>
