find_package(SWIG REQUIRED)
message(STATUS "FOUND SWIG_EXECUTABLE=${SWIG_EXECUTABLE}, SWIG_DIR=${SWIG_DIR}")
On Ubuntu and Windows this is just fine. it does output the correct SWIG_DIR

on macOS, it outputs a wrong path that's on the build machine

That cmake variable could be fixed by just doing SWIG_EXECUTABLE + "/swiglib" but the main problem is that the swig exe points to the wrong swig lib so any call to the exe would need to set the env variable SWIG_LIB (via ${CMAKE_COMMAND} -E env SWIG_LIB="${SWIG_EXECUTABLE}/swiglib" for eg)
