# 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.
