On MinGW, and if so details please?  (If on Cygwin, you should be
using the Cygwin install of Qt, and the directions are different
than I gave for MinGW.)

The context of your question about cl seemed to indicate you were
trying to use the cairo device for a MinGW build so my reply assumed
that.

I am not surprised that cl does not exist for the Cygwin case since
Cygwin tries to be as close as possible to the Unix platform case and
cl is a native Windows application.  With some fairly minor caveats
Arjen has had some good success on Cygwin with the cairo device
driver.  But he installed the Cygwin version of the pango/cairo subset
of GTK+ and you must do that as well for the Cygwin case.  I am now
wondering if you attempted to use instead a downloaded native Windows
versions of those libraries (that might be suitable for MinGW but
never for Cygwin), and this was the source of error messages about cl?

If/when you reply, please be explicit each time whether you are
running a build on MinGW or Cygwin and please also give all error
details including cmake options such as the generator you used, and
cmake output which normally gives exact locations where CMake found
libraries.  Also, for each such library found by CMake you should
double-check whether it is a native Windows version you downloaded or
a Cygwin library that is installed officially with the Cygwin
installer and adjust your PATH and other environment variables
carefully so cmake always finds MinGW libraries on the MinGW platform
and Cygwin libraries on the Cygwin platform.
