Add example for cross-build to android with CCI recipe

Hmmm, 🧐 I need to do some research on what the expected behavior is, i've never used this on Windows

foo/1.0: RUN: cmake -G "MinGW Makefiles" -DCMAKE_TOOLCHAIN_FILE="C:/J/w/Examples2.0_PR-113/21a5/535f/.conan/p/b/foofc270d89a49a2/b/build/Release/generators/conan_toolchain.cmake" -DCMAKE_INSTALL_PREFIX="C:/J/w/Examples2.0_PR-113/21a5/535f/.conan/p/b/foofc270d89a49a2/p" -DCMAKE_SH="CMAKE_SH-NOTFOUND" -DCMAKE_POLICY_DEFAULT_CMP0091="NEW" -DCMAKE_BUILD_TYPE="Release" "C:\J\w\Examples2.0_PR-113\21a5\535f\.conan\p\b\foofc270d89a49a2\b"

CMake Error: CMake was unable to find a build program corresponding to "MinGW Makefiles".  CMAKE_MAKE_PROGRAM is not set.  You probably need to select a different build tool.

https://github.com/android/ndk/issues/1581#issuecomment-920541042 Seems related but I am not sure is that's the problem here 🤔

@memsharded It seems the default CMake generator Conan is picking might not make sense for the cross-building to android scenario on windows.

I forced it to use ninja for all of them which seems to be passing now. I also noticed current example is untested on windows which is another option

The failure on linux seems unrelated

Asked Julius about this, we have two options

Update the Client CMake generator to return Ninja (which is the recommendation from google) for the windows to android case
Update the CCI recipe to expose the ninja (might be windows only)

conan-io / examples2
