BUILD.c

/***********************************************************
 * Name: builder.c
 *
 * Experimental C only buid system, idea inspired by:
 * https://github.com/tsoding
 *
 * TODO change to a header for each target plataform
 *      when it gets more complex??
 * TODO check args for target platform and bits, if no
 *      if no arg is provided it will build for the current
 *      one
 * TODO add auto zip release for Linux, because debian won't
 *      run the executable if it was compressed in Windows
 * TODO add current envoriment checks (compilers, libraries,
 *      etc)
 * TODO this is getting really ugly, it needs some refactoring
