Use relative bin and lib install paths.

CMake's install will combine the relative path with the
absolute path passed via CMAKE_INSTALL_PREFIX. This
shouldn't be handled in CMakeLists.txt files.

The state before resulted in absolute paths being
used in citygmlConfig.cmake. That prohibits prebuilding
the library and deploying it on other machines/paths.
