Describe the Bug

iothub_client_sample_mqtt_dm sample generates error while cross-compiling because of the include path "-I/usr/include/azureiot"

The actual error message is: "ERROR: unsafe header/library path used in cross-compilation: '-I/usr/include/azureiot'"

The path is set in the sample's CMakeLists.txt file:

set(AZUREIOT_INC_FOLDER "pi_device" "../../../serializer/inc" "." "/usr/include/azureiot" "/usr/include/azureiot/inc")
include_directories(${AZUREIOT_INC_FOLDER})

CMake project configured with the command cmake -S . -B corss_build -G Ninja --toolchain custom-toolchain.cmake -DCMAKE_BUILD_TYPE=Release -Duse_http=off -Dskip_samples=off

After giving a second thought for this, I think it's not very common use case to cross compile samples. Samples might be tested on the host system rather than in the target system. Using -Dskip_samples=on parameter for CMake might the desired way to get the libraries for the target system.
