Test: tests fail with old CMake versions
The variable MPIEXEC_EXECUTABLE
created by the CMake FindMPI
module exists only in recent CMake releases (>3.10). The variable is used by melissa-da_set_env.sh.in
. With older CMake versions all MPI-based tests fail.
The problem was already fixed in commit a4dd0c12 but I am opening this issue because it was not obvious why the tests inside the continuous integration environment succeeded while they were known to fail after reading the CMake 3.7 FindMPI
documentation.
