Hi Alex,

the problem occurs only if I call cmake 2 times with the same arguments:

  cmake -DCMAKE_C_COMPILER=i386-mingw32-gcc -DCMAKE_CXX_COMPILER=i386- 
mingw32-g++ -DCMAKE_SYSTEM_NAME=Windows -DCMAKE_INSTALL_PREFIX=C:/usr ..
### OK

cmake -DCMAKE_C_COMPILER=i386-mingw32-gcc -DCMAKE_CXX_COMPILER=i386- 
mingw32-g++ -DCMAKE_SYSTEM_NAME=Windows -DCMAKE_INSTALL_PREFIX=C:/usr ..
### ERROR

The after the first time with SystemName and compiler settings, I  
should only run:

cmake ..
# then it works.

Sorry about the noise.

About this SystemName "Windows-gcc"
It is also listed as example on this page:
