FindSherpa.cmake Improvement, master branch (2020.06.03.)
This is a sibling of !683 (merged). It achieves the same effect, just using a built-in feature of the lcg_external_module(...)
function. (One which is not present in the 1.0 branch.)
It also sets up the ${SHERPA_Sherpa_EXECUTABLE}
and ${SHERPA_Sherpa-config_EXECUTABLE}
cmake variables, which may prove useful in the future.
