Fix configuration with CMake >= 4:

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.

The fix for CMakeLists.txt and ExampleDriver/CMakeLists.txt is from:

https://github.com/pothosware/SoapySDR/commit/fbf9f3c328868f46029284716df49095ab7b99a6

python/CMakeLists.txt is not yet fixed upstream; see:
