TIFF::CXX is assumed to be built into libtiff when MSVC is used

In FindTIFF.cmake, TIFF::CXX, under MSVC, is assumed to be built into the main tiff library, libtiff, but in reality, it is not built there.

We made the module work by removing that logic. Can anyone else confirm the bug so I can create a merge request?


See CMake MR 4934 for where that was added. Please open an issue and Cc the original MR author.
