libtiff fails to build when opengl/glut are found
Seems related to these errors:
- https://bugs.orfeo-toolbox.org/view.php?id=1306
- https://ubuntuforums.org/showthread.php?t=1703770
When OPENGL_GLU_FOUND OPENGL_GLU_FOUND and GLUT_FOUND libtiff forces HAVE_OPENGL to be true. This caused me to encounter the error: GLUT_Xmu_LIBRARY NOTFOUND
Ideally, there would be an option to turn opengl off in libtiff itself.
Following the directions in the second link, I was able to continue by installing the packages
sudo apt-get install libxmu-dev libxi-dev
but obviously forcing the user to install packages isn't an ideal fix for a superbuild, so it might be a good idea to incorporate the lines from the first lines that set an initial cache with opengl forced off, set(WITH_OPENGL "FALSE" CACHE BOOL "Initial cache" FORCE) or we can make a patch for libtiff that fixes the issue and might eventually be pushed to the parent repo.
Those packages are required for things like Qt and VTK, for example so it's not a huge deal for further to require. That said, I agree libtiff should have a disable option an and Gl should not be required by it.
I've been bit by the counter some times on systems where GL isn't installed but other packages are.

Its more the GLUT dependency than the OpenGL dependency. Isn't GLUT depricated? I have OpenGL on my system, what I didn't have was libxmu and libxi, which I believe only GLUT cares about. I might be wrong though.
