Cross compile for embedded ARM using preset file does not create cacheVariables before calling CMakeLists.txt

[davepregan]

Brief Issue Summary

Using cmake --preset debug works from the command line. It does not work from CMake:Configure. Some command line defines provided by preset cacheVariables are not set before calling root CMakeLists.txt. CMakeLists.txt outputs a message which indicates that the define has not been provided.

Thanks for letting us know @davepregan ! Could you provide a repro project so that we can investigate?

This definitely seems to be stemming from our extension since it reproduces with the extension but not on the command-line, so a repro project would be very useful. Thanks!

[davepregan]

Well I don't really understand what is happening here. I started to prepare a repro project and re-ran the generation/build. This time it worked but the command line seems to have changed
