Tutorial: Restore USE_MYMATH in place of MY_MATH (!7829) · Merge requests · CMake / CMake

In !7577 (merged) we replaced some uses of USE_MYMATH with MY_MATH. Restore the former name for consistency with the rest of the tutorial.

Thanks to @jason-m-reich for the highlighting this issue and writing the initial change.

Backport: release
