[B2Qt 6.3.0] Kit not registered correctly when trying to build a cmake application for the first time

Steps to reproduce:
1. Install B2Qt 6.3.0 toolchain (apalis-imx6 used in testing)
2. Open Qt Creator 7.0.1 and a cmake based application (widget application used when testing)
3. Build the example

Expected result:
The example builds

Actual result:
The example does not build, and application output shows that the kit is not registered correctly. A rebuild however helps to solve the build issue. See the attached screenshot for the exact build error shown.
