Cannot configure/use azure-sdk-for-cpp as per README

[felix-kolbe]

Describe the bug I followed the README.md to include azure-sdk-for-cpp in my project, but the configuring step fails.

First I used the FetchContent approach to skip any vcpkg. I created a test project for the sample to have and share a MRE: my azure-sdk-for-cpp-demo.

(I also tried to use the vcpkg way, as per README.md, but it was not working, too.)

Exception or Stack Trace Excerpt from build.log:

-- Using vendored uamqp
CMake Error at build/_deps/azuresdk-src/sdk/core/azure-core-amqp/vendor/azure-uamqp-c/CMakeLists.txt:56 (find_package):
   Could not find a package configuration file provided by
   "azure_macro_utils_c" with any of the following names:
 
     azure_macro_utils_cConfig.cmake
     azure_macro_utils_c-config.cmake

To Reproduce Steps to reproduce the behavior:

rm -rf build && cmake -S . -B build 2>&1 | tee logs/build.log

Code Snippet The CMakeLists.txt I used. Includes other variants I tried, as per README.

endif()

add_executable(${PROJECT_NAME} sample.cpp)

# target_link_libraries(${PROJECT_NAME} PRIVATE Azure::azure-identity)

Expected behavior A successful CMake configuration pass. And eventually a built sample executable.

Setup (please complete the following information):

• OS: Ubuntu 22.04 Docker DevContainer (see my MRE's Dockerfile for details)

  $ uname -a
  Linux b9994a31fba2 5.15.133.1-microsoft-standard-WSL2 #1 SMP Thu Oct 5 21:02:42 UTC 2023 x86_64 x86_64 x86_64 GNU/Linux
  

• IDE : none/shell, or VS Code
• Version of the Library used: Branches main as well as storage-november-release (which equals azure-storage-blobs_12.10.0 and other storage tags)

Additional context I suspect the issue is within the sub component sdk/core/azure-core-amqp which somehow brings its own azure-uamqp-c, but the latter is plainly copied in there, so its submodules from .gitmodules -- which include the missing azure-macro-utils-c -- cannot be initialized and found at all.
