Try
set(REQUIRED_OPTION "--block \$ENV{COBALT_PARTITION}")
That way you inhibit the variable expansion at CMake time, but the output
of the expansion has had a level of indirection removed, in the usual
shell-script way. Then I expect add_test will look like your hand-edited
version.
set(EXE_CMD ${RUNJOB} ${RUNJOB_NPF} ${REQUIRED_OPTION}

FindMPI.cmake has a set of somewhat standard variable names that might make
sense for you to follow, even though that module probably won't be useful
for finding runjob, because it might do so at some future time.
