Symlink problem using catkin_tools==0.4.2: because the location of generated manifest.l is unusual?

[wkentaro]

With catkin_tools==0.4.2, it raise below warnings, this is annoying and it seems dangerous because the md5sum is different for same manifest file.
I wonder this is because of the unusual location of manifest.l generated by cmake.
manifest.l needs to be located under devel/share/ros/roseus directory, but usual files are located under devel/share/[BUILDING_PACKAGE].

Any idea how to fix this?

PS.
Currently I'm using without symlinking by catkin config --merge-devel.

The difference is only the header
