Hi,
So, that means aprun is not in your path? In that case you could try the
same, but give the path where cmake can find aprun:
find_program(MPIEXEC aprun PATHS /path/to/aprun)
(see cmake --help-command find_program for more info)
I tried the same myself (not with aprun but another binary), and it
worked as expected here. Since MPIEXEC is already found, the next
find_program call inside FindMPI.cmake does not search again but use the
binary found (as I understand it).
Cheers,
Yngve
