[Trilinos-Users] trouble with mpi libraries

[Dicharry, Will]

Hi William,

Did you pass -DTPL_ENABLE_MPI=ON as well as -DMPI_BASE_DIR? If so, was
Cmake able to locate your wrapper compilers? You can check this by looking
for something like

Detecting CXX compiler: /path/to/mpiCC

In the initial Cmake output.
