Could not find qmake configuration file win32-msvc

[easythrees]

I have one of the sample programs for a QWidget, the Analog Clock one. When I try to build it, I get an error:

Could not find qmake configuration file win32-msvc
Error processing project file: C:\work\Qt_Sample\analogclock.pro

I launched the VS 2015 Developer Console, and ran the qmake.exe tool like so:

qmake.exe spec win32-msvc -tp vc

Any ideas what's going on here?

@easythrees Shouldn't it be

qmake.exe -spec win32-msvc -tp vc

?
So, a dash before spec.
