Issue and Fixing Patch - CMake tests on macOS with M chip

Development

The make test command fails on macOS with M chip, because of the test BuildDepends failing.

In order to reproduce the issue, you need to make sure Rosetta is not installed on your machine. Otherwise the test will succeed.

The reason behind this fail is because the binary is not compiled for arm architecture. The following patch works on Apple with M chip, but I’m not sure about the minimum required version of XCode for that, neither if this would work on mac computers with Intel chips:

diff -ruN a/Tests/BuildDepends/Project/CMakeLists.txt b/Tests/BuildDepends/Project/CMakeLists.txt

@Gaahfy thanks. Please try CMake MR 9277.

Thanks a lot @brad.king for the Merge request

Works well on macOS Sonoma 14.3.1 Macbook Pro M2 with XCode 15.2 (15C500b) - Rosetta not installed
