[CMake] cmake prebuilt binaries won't work if bin folder is renamed.

You will need to rename the directory containing bin; the share folder
scripts is often very dependant on the bin (or vice versa) ...
better to just keep like 'cmake' and then 'cmake-3.xx' directories
containing the whole cmake package...
