Wrong CMAKE PREFIX

There's a problem running CMake projects. The CMAKE_PREFIX contains path of previous installation of Qt 6.8 Beta2.

see 01-cmake-prefix-wrong.png

Have edited the prefix to get rid of the old path

see 02-cmake-prefix-edited.png

Build - Rund CMake asks me to apply. hit apply

see 03-cmake-prefix-apply-changes.png

but getting error from build and wrong prefix back

see 04-cmake-prefix-wrong-back.png

and the build error from Ninja trying to run from an old installation

see 05-ninja-error.png

workaround: create the old folder and copy Ninja into this folder

have only noticed on macOS, not on Android or iOS
