Cmake build error

[StefanGu65]

When trying to add ADU to the rest of the IoTHub features, I run into cmake issues.

Top Level:
message(PROJECT_SOURCE_DIR="${PROJECT_SOURCE_DIR}")
add_subdirectory(azure-iot-sdk-c out)
set(azure_c_shared_utility_DIR "${PROJECT_SOURCE_DIR}/azure-c-shared-utility/configs")
add_subdirectory(azure-c-shared-utility)
#add_subdirectory(iot-hub-device-update )
add_subdirectory(iot)
include_directories(.)

Output:
CMake Error at azure-c-shared-utility/configs/azure_c_shared_utilityConfig.cmake:11 (include):
[cmake] include could not find requested file:
[cmake]
[cmake] /home/stefan/workspace/TCU/azure-c-shared-utility/configs/azure_c_shared_utilityTargets.cmake
[cmake] Call Stack (most recent call first):
[cmake] iot-hub-device-update/src/adu-shell/CMakeLists.txt:45 (find_package)
[cmake]

Question:
I cannot find a "azure_c_shared_utilityTargets.cmake" anywhere in the main branch.
Am I missing something?
