FNCUIPack lazarus on windows missing units

I cannot install fncuipack ( under windows 10. Lazarus trunk + fpc-3.2.0 (if that matters at all).
There is missing unit Win32Proc and Win32Extras so uipack cannot be installed. Any hints ?

Resolved, sorry for the false error. I'm installing fncuipack under win32 but with qt widgetset, and win32proc & win32extras are win32 widgetset part only.
It's easy to fix it: just {$IFDEF LCLWin32}Win32Proc,Win32Extras{$ENDIF} around and it works.

Thanks for informing
