Subject: cmake: update uninstall target

- update cmake_uninstall.cmake.in from
  https://cmake.org/Wiki/CMake_FAQ#Can_I_do_.22make_uninstall.22_with_CMake.3F
  and move the file to /CMakeScripts
- on WIN32 simply delete the whole distribution directory
  (should be sufficient ant the script version is unbearably slow)
