I've found that instead of using include_directories(),
set_directory_properties (INCLUDE_DIRECTORIES) works for this, at
least on Windows.

Still have this. Also, there is a rule to update the project based on
CMakeLists.txt, and this won't work in an installed situation. Can I
get rid of the check timestamps against CMakeLists.txt?
