Include dirs var becomes strange character

[mortenfyhn]

Hi again!

In one of my projects, I'm getting an error like this

<my project>: CMakeLists.txt(60): warning: target_include_directories() has foreign PUBLIC path '${�_INCLUDE_DIRS}'

where the strange character before _INCLUDE_DIRS shows up differently in different places.

In my terminal it shows up like this:

and if I copy from my terminal into my editor, it looks like this:

In the CMakeLists.txt file, it's just ${MAVLINK_INCLUDE_DIRS}.

I think this might be a false positive caused by some parsing error.

Yeah, that's a bug I introduced with the last release. And of course it is the one thing I did not test properly because I was lazy and thought it would be working.

For the record, it is not a false positive, it's just a garbled output message. What it means is that you should avoid putting find_packaged() paths into INTERFACE and PUBLIC includes, because if you export the targets, CMake will hard-code those paths in the exported config.

I see, thank you! Sounds familiar.

I guess I still have some things to learn about cmake and catkin-cmake, but that's part of the reason why this project is so useful.
