Or can I get a list of all the targets(created and imported) and then get the list of "include_directories" from those targets?

The clang compilation database might give you what you need - it’s what several autocompletion tools already use. To generate this, just pass  -DCMAKE_EXPORT_COMPILE_COMMANDS=ON when running cmake. You would have to extract the -I options from the command entries, I guess.
