You've said that this project was merged into UE4 and i see it is merged but the code differs drastically. I wanted to add a "force include" alternative from VS project via CMake's target_precompile_headers in generation code to make IDE know about ENGINE_API, <YOUR_PROJECT>_API and other definitions, it won't highlight code correctly without them.
VS does this:

When i did this in CMake:

CLion started parsing source files correctly but this will work until you regenerate the code
The problem is that your project contains a function for CMake code generation but UE4's one doesn't. I just literally can't understand where it generates the CMake code
Info in Plugins window in UE4 still points to your organization and I don't know where to address this issue to
