You can use jom, or gmake.

Jom is an nmake replacement that can do parallel builds done by the Qt 
folks, the download can be found here:
ftp://ftp.qt.nokia.com/jom/jom.zip

For gmake, you need cygwin installed, but you need to use the gmake from 
here:

Older cygwin:
http://www.cmake.org/files/cygwin/make.exe
Cygwin 1.7:
http://www.cmake.org/files/cygwin/make.exe-cygwin1.7

For gmake use the Unix Makefiles generator, and make sure make is in 
your PATH.  For jom use the NMake Makefiles generator, and then run jom. 
  CMake CVS has a jom generator, but the NMake Makefiles one should work 
fine.
