HI Alan, Thanks for your suggestion. I wish it were that easy, but the bundled VS CMake is pretty tightly coupled and you can’t easily replace it. I believe they also rely on one or two features they might have added or enabled in their build of cmake - so they are currently maintaining a divergent fork that hopefully will eventually get mainlined (?). In the meantime, it looks like I just need to switch to set_target_properties for 3.8 instead of trying to use target_include_directories on an IMPORTED target. This seems to be working so far.
