[CMake] Eciipse and multiple configuration

[Andrea Galeazzi]

I followed the tutorial at 
http://www.cmake.org/Wiki/Eclipse_CDT4_Generator in order to generate an 
Eclipse project.
The only difference is that I select eclipseCDT - MiinGW Makefiles 
instead of eclipseCDT -Unix Makefiles".
What I don't understand is how can I manage multiple configurations in 
the same project (for example Debug/Release) if the cmake-gui requires a 
specific CMAKE_BUILD_TYPE.
Sorry but I'm a CMake newbie......
