Cannot find source files: modbus-reply.c & modbus-reply-mapping.c

When building in MSYS2, it cannot find the files: src/modbus-reply.c and src/modbus-reply-mapping.c. If these files are excluded from the assembly in CMakeLists.txt, then the library is built successfully. I cannot yet say anything about whether this code works or not.

Hmm I might have forgotten to adjust that while rebasing the commit history. I will check and notify you.
