Error running qmake

[OneMHz]

When I try to run the qmake command, I just get

QMAKESPEC has not been set, so configuration cannot be deduced.
Error processing project file: C:/.../android-sdk/tools/remote/src/desktop/remotejs.pro

I just downloaded and installed the whole QT sdk. I had a few copies of qmake.exe come up, but the installer didn't put any of them in the path, so I'm not sure which is correct.

You can specify a spec directly, but which spec would depend on your build environment. Are you building with Visual Studio? E.g.:

qmake -spec win32-msvc2010

The value of the spec might differ for your environment.
