[gdal-dev] iOS patch for GDAL 3.5 requires modification for Mac Catalyst

[Robert Coup]

Hi,

The patch at the end of my reply builds & tests ok on my environment (macOS
12.5.1 + arm64).

Are you using https://github.com/leetal/ios-cmake or do newer versions of
CMake now have support for Catalyst? (from
https://gitlab.kitware.com/cmake/cmake/-/issues/20132 it seems not)

How do the varios combinations of CMAKE_SYSTEM_NAME=Darwin|iOS, APPLE,
UNIX, etc work under Catalyst?

Rob :)
