[CMake] Which targets are affected by CMAKE_INCLUDE_CURRENT_DIR_IN_INTERFACE?

[Sebastian]

Hi,

The documentation https://cmake.org/cmake/help/v3.10/variable/CMAKE_INCLUDE_CURRENT_DIR_IN_INTERFACE.html
states "CMake automatically adds for each ... target".

I assume the variable has directory scope. So it affects all targets in that directory? Or only targets which are created (by add_library, for example) AFTER setting the variable?
In other words: Which commands evaluates the variable? add_library? target_include_directories?

The documentation could be a bit more clear on this...

Thanks,
Sebastian
