Makefile generator, implemented using C + + and boost

Today I learned about the Boost file traversal feature, and at the same time found the GNU compiler has the-MM option. Being able to generate dependencies on its own initiative, I wrote a makefile generator using the above two points.

The ability to generate a generic makefile of a single executable file. The Windows+mingw+boost environment is used. Assuming that Linux is used, it is only necessary to change Del to RM related operations at the two system calls in the program and the clean tag generation.

Now changes to the Linux version number. The version number of the download is Windows.

The following is the source code:

Makemake.cpp:
