Usually the problem is that the application CMakeLists.txt or other custom CMake snippet code is not obeying the bitbake generated toolchain.cmake file and the variables set there. I presume your application recipe is doing "inherit cmake". The application side can for example overwrite the various variables which set the cross compiler sysroot. Cheers, -Mikko
