MC_SOURCEDIR
The MC_SOURCEDIR macro specifies the target directory for the generated resource compiler script (.rc file) and the generated binary resources (.bin files) that the resource compiler script includes.
The Build utility passes MC_SOURCEDIR as the -r option to the Message Compiler (Mc.exe). By default, the path is set to PASS0_SOURCEDIR.
Use the MC_FLAGS macro to specify command-line parameters to pass to the Message Compiler (Mc.exe).
