VWR-24247: develop.py configure still searches for the wrong header file when checking for Tut

The viewer code includes "tut/tut.hpp" everywhere, so that is what we
should search for when determining an include path for this header.
This just searches in the usual places, including the paths provided
through CMAKE_INCLUDE_PATH, and will find tut/tut.hpp: exactly what
we need.
