[CMake] cmake MinGW WinXP DevCPP Problems

[David Cole]

Running CMakeSetup from the same environment that gcc and make run in 
should work when you're using MinGW. I'm not familiar with Dev-Cpp : do 
you run it from an MSYS shell? Or does it know about MinGW independent 
of having MSYS installed?

Try again with a fresh directory containing just your cpp, h and 
CMakeLists.txt file. Launch CMakeSetup from a command prompt / MSYS 
shell that has the environment set to run gcc... (Perhaps launch it from 
within Dev-Cpp? Can it launch external tools easily?)

Sometimes when you've run cmake and CMakeSetup on the same tree, you get 
confused about the state of things and it's easier to start fresh.
