[CMake] Faking a library

[Nick Hutchinson]

As of 2.8.12, you can set target properties on an imported library to
specify its include directories, compile options etc, and these will be
automatically propagated to any other target that links to it via
target_link_libraries(). No more tedious faffing about with global
variables like GTEST_INCLUDE_DIRS, GTEST_LIBRARIES etc. It's really quite
nice.

Check the 2.8.12 CMake docs for target properties that start with
"INTERFACE".
