Mario,
based on your question you seem to be fuzzy on a basic fact, that is,
the "msys" packages
are a separate platform from those with the mingw-w64 designations. msys
is there
principally to support the shell and build system. Often enough, a
configure scheme will use
python as a utility and so yes python and perl, from /usr/bin tree, will be
useful.
The mingw platforms does not include the posix compatibility layer of
msys.
So mingw programs and constituent libraries are kept separate from those
in support of msys.
the /mingw64 directory tree etc. So the msys package "cmake" is overall
completely incompatible with
what you are doing - and it is built with "MSYS Makefiles" generator
removed to help clue you into that fact.
When you install /mingw64/cmake you will have much better results: cmake
will awake in the environment
it was meant to build from.
You should probably un-install the msys cmake, gcc, fortran versions that
would get you into trouble.
