/usr/bin/ar and /usr/bin/ranlib. I need it to discover the ones with the mingw
prefix.

The command I use for cmake is simply cmake -DCMAKE_TOOLCHAIN_FILE=<file>
<sourcepath>. For better understanding what I do wrong, I attach both the now
working toolchain file I have, and the non-working one.
With the non-working one I get the following grep result afterwards:
$ grep RANLIB **/*
CMakeCache.txt:CMAKE_RANLIB:FILEPATH=/usr/bin/ranlib
CMakeCache.txt://ADVANCED property for variable: CMAKE_RANLIB
CMakeCache.txt:CMAKE_RANLIB-ADVANCED:INTERNAL=1
CMakeFiles/CMakeCCompiler.cmake:SET(CMAKE_RANLIB "/usr/bin/ranlib")
CMakeFiles/CMakeCXXCompiler.cmake:SET(CMAKE_RANLIB "/usr/bin/ranlib")
CMakeFiles/CMakeFortranCompiler.cmake:SET(CMAKE_RANLIB "/usr/bin/ranlib")
With the now working one I get the following result:
$ grep RANLIB **/*
CMakeCache.txt:CMAKE_RANLIB:FILEPATH=/usr/bin/i486-mingw32-ranlib
CMakeCache.txt://ADVANCED property for variable: CMAKE_RANLIB
CMakeCache.txt:CMAKE_RANLIB-ADVANCED:INTERNAL=1
CMakeFiles/CMakeCCompiler.cmake:SET(CMAKE_RANLIB "/usr/bin/i486-mingw32-
ranlib")
CMakeFiles/CMakeCXXCompiler.cmake:SET(CMAKE_RANLIB "/usr/bin/i486-mingw32-
ranlib")
CMakeFiles/CMakeFortranCompiler.cmake:SET(CMAKE_RANLIB "/usr/bin/i486-mingw32-
ranlib")

OK, perhaps I use different cmake version? I have 2.8.8 installed.
