* Update to install CGAL as header-only
I think the issue #2471 would be completely solved, if vcpkg installed CGAL as header-only. That way, the installed `CGALConfig.cmake` would search for its dependencies, instead of hard-coding their path in the file.
* Bump the version
* Fix the cleaning
Once CGAL is header-only, no binary library is created, and the
`debug/` directory got empty.
This commit fixes the cleaning: now the whole `debug/` directory is
removed.
* Update to 4.13 and minimize the qt5 dependency.
* [cgal] Fix license installation for new git repo layout
* [cgal] Remove vcpkg_test_cmake until x64 can be fixed
