title: Possible to add an imported library to target_link_libraries that takes care of include directories too?
body: <p>somehow I am struggling with finding out whether it is possible to define an imported library in CMake, specifying target properties (include_directories and library path) and hoping that CMake will append the include directories once I add that project to target_link_libraries in another project.</p>
  
  <p>Let's say I have an imported library in a file called Module-Conf.cmake:</p>
  
  <pre><code>add_library(mymodule STATIC IMPORTED)
  set_target_properties(mymodule PROPERTIES IMPORTED_LOCATION "${OUTPUT_DIR}/lib")
  set_target_properties(mymodule PROPERTIES INCLUDE_DIRECTORIES "${OUTPUT_DIR}/include")
  </code></pre>
  
  <p>And in a project I add the dependency:</p>
  
  <pre><code>include(Module-Conf)
  target_link_libraries(${PROJECT_NAME} mymodule)
  </code></pre>
  
  <p>Will CMake append the include_directories property to the include path? Right now I cannot see the path so it seems that I have to do it by myself by using get_target_property?</p>
  
  <p>Question: Can I do some CMake magic to automatically append the include to the include directories of another project?</p>
  
  <p>Thanks a lot.
