# Lua can be compiled as either C or C++.
# Default configuration is C, set COMPILE_AS_CPP to ON to use C++.
# See http://stackoverflow.com/questions/13560945/c-and-c-library-using-longjmp for why would you want to do that.
# Primary differences:
# - Exceptions will be used instead of setjmp/longjmp
# - The name mangling for functions will be C++ instead of C.
# - This is a source-incompatible change because extern "C" is chosen by the including application.
# - The lua.hpp header will not be available.
