commit 2fdebacac9d70c372e0b6926ffd4ff73728c93ec
Author: Paul Cercueil <pa...@cr...>

CMake: Support romdisks in C++ projects (#677)
* bin2c: Generate code compilable with C++ compiler
Mark the variables as "extern C" so that the generated source file can
be compiled with a C++ compiler and still link properly with KallistiOS.
Signed-off-by: Paul Cercueil <pa...@cr...>
* CMake: Support generating romdisk in C++-only projects
When the project is C++ only, any .c file added to the target sources
will be ignored by CMake. This meant that the source file generated by
kos_add_romdisk() macro would not be compiled.
Address this issue by changing the extension of the generated source
file to .cpp when a C++ compiler is used.
