[CMake] "CMAKE_MAKE_PROGRAM is not set"

[Stephen Collyer]

I have some code that I've delivered to a 3rd party
who is now trying to build it. They're using Vista
and a Visual Studio 2008 environment, with cmake 2.6.1

They're getting the following errors when trying to run
cmake. It looks to me like an environment problem of some
kind, but I've never seen it before:

Can someone suggest what cmake is lacking here ? I
guess it's failing to find nmake for some reason.
