Right got it, the problem occurs when I add the target_link_libraries command to the dependent project. The attached tar.gz contains my not working example source, layout: This will show the error where it is using the -isystem to include the include directories, if you comment out the target_link_libraries command in ex/CMakeLists.txt the build will succeed and -I will be used to include the include directories.

My first simple example worked, so I looked at adding an imported target, as this is what my actual script has, to install the dependent modules but this also worked as expected.
