Comment:
I think the packages are ready for review!

`tetgen` binary is now built directly in CalculiX-cgx package.

I took all your comments into account (with one exception: I still use `make` instead of `cmake` for `tetgen` binary, because it's more practical since I can't use the `cmake` build method of `xbps-src`).

I also added a `-O2` flag in FFLAGS of CalculiX-ccx.
