CMake include path for generated Sources differs from actual generated Sources location

The CMake project generated by UnrealBuildTool does not specify the (correct) directory for files generated for game classes. This happens when generating the CMake files from within the editor using CLion code accessor and then compiling the project from within the editor.

When tested in 4.19.2 (CL-4033788) neither of the specified paths were generated.

1. Open the UE4 Editor and create a Basic Code Project
2. Generate CMake project files (e.g. set editor source accessor to CLion or run ".../UnrealBuildTool.exe -cmakefiles -projec=".../MyProject.uproject" -game -engine -progress)
3. Open project with CLion

Results: Code generated for game classes is placed in `<ProjectDir>/Intermediate/Build/Linux/<SomeId>/UE4Editor/Inc/<ProjectName>`. However, the CMake project () specifies `<ProjectDir>/Intermediate/Build/Linux/<SomeId>/<ProjectName>Editor/Inc/<ProjectName>` instead of the one mentioned before as an include path. When opening the project in CLion this results in the IDE being unable to find the projects "*.generated.h" headers.

Expected: Opening the project in CLion doesn't lead to "Header not found"-type errors.
