Hello,
I am trying to build sample application on for mimxrt1064_evk on windows 10. I seem to have installed everything, but i still get this error:

You need to pip3 install pyelftools or, even better, pip3 install zephyr/scripts/requirements.txt

Reopening since I missed some of the input

I tried this locally and works fine on a Windows 10 machine. It might be that you have multiple Python 3 installations and CMake is picking one where you don't have pyelftools installed.
