CMake 4 compatibility

[carlwgeorge]

CMake 4 drops compatibility with CMake older than 3.5, and now returns this error:

CMake Error at CMakeLists.txt:1 (cmake_minimum_required):
  Compatibility with CMake < 3.5 has been removed from CMake.

  Update the VERSION argument <min> value.  Or, use the <min>...<max> syntax
  to tell CMake that the project requires at least <min> but has been updated
  to work with policies introduced by <max> or earlier.

  Or, add -DCMAKE_POLICY_VERSION_MINIMUM=3.5 to try configuring anyway.

To allow building with CMake 2.8 through 4, update cmake_minimum_required to the min...max syntax.
