FindSherpa.cmake Improvement, 1.0 branch (2020.06.03.)
Made FindSherpa.cmake
add the Sherpa executables to the PATH
environment variable. Did this simply by setting up the SHERPA_BINARY_PATH
cmake variable based on the location of the Sherpa(-config)
executable(s).
This is necessary to avoid hardcoding the location of Sherpa-config
into our C++ code at build time.
