Move all build steps into CMake

[BogdanTheGeek]

most of the other scripts could be moved to cmake to make the whole project more cross platform, but this a start.

Looks good but getting a build error:

wnparvect.cpp:1:10: fatal error: 'wnlib.h' file not found
    1 | #include "wnlib.h"
      |          ^~~~~~~~~
1 error generated.
make[2]: *** [Source/tmModel/CMakeFiles/tmmodel.dir/wnlib/conjdir/wnparvect.cpp.o] Error 1
make[1]: *** [Source/tmModel/CMakeFiles/tmmodel.dir/all] Error 2

Are cmake and make -j8 supposed to be run from the /build directory?
