NSIS package generation fails when OPTION_BUILD_EXAMPLES is disabled

[j-o]

I haven't quite figured out what the problem is, but it has something to do with NSIS trying to modify the non-existing "examples" component. See NSIS log below

Please experiment with the options in the "Package Components" section of the package project. Maybe removing "examples" from CPACK_COMPONENTS_ALL does the trick? In that case we have to insert ifs to check for each option separately.
