What would be required in such a file? Currently I have cat << EOF > $BUILD/$PFUNIT/cmake/Flang.cmake set(CMAKE_Fortran_FLAGS_DEBUG "-g -O0 -Mbounds") set(CMAKE_Fortran_FLAGS_RELEASE "-O3") set(CMAKE_Fortran_FLAGS "-Mpreprocess -Mfreeform -Mstandard") EOF Configuration was successful, but make failed.
