Hello, On a Cray XE6, I am using find_package(MPI REQUIRED) in my CMakeLists.txt. It correctly finds all of the MPI stuff, except that it sets the MPIEXEC to the login node mpiexec command. I would like to override this behavior and set the MPIEXEC command to the "aprun" wrapper, but it is not working. I have tried using set(MPIEXEC "aprun") both before and after the find_package(MPI REQUIRED) in my CMakeLists.txt.
