Does the target_include_directories() command strip out duplicate paths added?

I don’t recommend using . and .. in your include directories; the working directory of the compiler is different for different generators, so they don’t mean the same thing. I think using absolute paths here would generally make things more readable and be closer to what you want.

It shouldn’t matter. The target_include_directories() command internally converts relative paths to absolute before storing them in the INCLUDE_DIRECTORIES target property. It treats relative paths as being relative to the current source directory.
