If they have C++ linkage then they need to be called with a C++ compiler
with compatible ABI. If you want to mix compilers with different C++
ABIs (such as gcc and MSVC) then you need to use C linkage.

Then you need C linkage, which means you have no choice but to enclose
the code in "extern C" (or compile it with a C compiler of course.) If
you really can't modify the source.cpp file then I still don't see why
you can't do something like:
extern "C" {
#include "source.cpp"
}
