[gdal-dev] libtiff v4.5.0 release candidate available

[Kai Pastor, DG0YT]

It is probably the best and cheapest what they could do with introspection.

The ultimate way out is to export CMake config in a compatible way so 
that *future* versions of FindTIFF.cmake can use it. (This is already 
done for CURL.) As a positive side-effect, this helps to properly carry 
transitive usage requirements for static linkage and to deal with 
multi-config generators.
