Thanks for your work!

There is an issue with tiff_vers.h:

The new linebreak style of the TIFF_VERSION_STR definition breaks version detection in CMake's FindTIFF.cmake, leaving TIFF_VERSION unset (in CMake). Some packages rely on this variable. E.g. openimageio in vcpkg:

-- Found TIFF
CMake Error at src/cmake/checked_find_package.cmake:154 (if):
  if given arguments:

    "VERSION_LESS" "4.0"

  Unknown arguments specified
Call Stack (most recent call first):
  src/cmake/externalpackages.cmake:90 (checked_find_package)
  CMakeLists.txt:141 (include)

which probably comes from some

if(${TIFF_VERSION} VERSION_LESS "4.0")

I would suggest to restore a formatting which doesn't break existing CMake code.

Regards, Kai
