Build failure at rcc step on 5.12.9 and 5.15.0 using VSTools 2.5.2

Please refer to forum:

https://forum.qt.io/topic/116655/5-12-9-build-failure

I attach the VS project file into which had manually to add Macros for QtToolsPath 

Note also that there were a lot of droppings from 5.12.8 initially in the VS Macros, but they appear to have gone now.
