/**
* \brief Return the CXTranslationUnit for a given source file and the provided

* '-o <output file>' (both '-o' and '<output file>' are ignored)
*
* \param CIdx The index object with which the translation unit will be

* \param num_clang_command_line_args The number of command-line arguments in
