Set includes and libs on object targets

Browse Source 
Instead of using the global `include_directories()` and
`link_libraries()` calls use the target versions
`target_include_directories()` and `target_include_libraries()` with
`PRIVATE` keyword instead.

The dependencies are libraries only, the headers are added to the build
instructions in a separate call. So the `target_link_libraries()` calls
are not needed for the object-libraries to be built.
