CrossCompile com CMAKE e Mingw

Question

Eu fiz um arquivo toolchain cmake para construir para o windows x86 e x64 do linux usando o mingw. Construir um projeto para o alvo do Windows x86_x64 funciona como um encanto, mas para o Windows i686 da mesma forma que eu construo o último me dá um erro.

construção para i686:

cmake -DCMAKE_TOOLCHAIN_FILE=../vendor/Libellum/Win32/gcc-cross-compiler-i686.cmake ..

erro:
