Complete quoting for parameters of some CMake commands

[elfring]

Some parameters (like "${PCL_SOURCE_DIR}/resources" and "${CMAKE_CURRENT_SOURCE_DIR}/include") are passed to CMake commands in your build scripts without enclosing them by quotation marks. I see that these places will result in build difficulties if the contents of the used variables will contain special characters like spaces.

I would recommend to apply advices from a Wiki article.
