Summary:
The purpose of this patch is to make identifying missing dependencies clearer to the user.
`find_package` will report if a package is not found, that output, combined with the exiting
status message, is clearer than not having the additional verbosity.
If the SWIG dependency is required {LLDB_ENABLE_PYTHON, LLDB_ENABLE_LUA}
and SWIG is not available, fail the configuration step. Terminate the
configure early rather than later with a clear error message.
We could possibly modify:
`llvm-project/lldb/cmake/modules/FindPythonInterpAndLibs.cmake`
However, the patch here seems clear in my opinion.
