Comment (by frederic.devernay@…):

 The following fix in CImg.h is the most portable solution.
 Got the idea from the OpenCV source code:
 https://github.com/Itseez/opencv/commit/33c26a93c6d97013b14e7dd080a347e242ef7f37
 Hopefully, David will include this in the next CImg release.

 Anyone who wants to include tiff.h or tiffio.h in a portable way should do
 this.
