using onnxruntime via fetch_content

[r4mtor]

I would like to use the onnxruntime with a static library or access the sources in my CMakeLists.txt file via fetch_content. The fetch content seems to work, but it seems that there is a problem when resolving nsync::nsync_cpp

Here is my CMakeLists.txt

cmake_minimum_required(VERSION 3.14)

# Project setup
project(MiniONNXRuntime CXX)

# Set C++ standard
set(CMAKE_CXX_STANDARD 23)
set(CMAKE_CXX_STANDARD_REQUIRED ON)

# Fetch ONNX Runtime source code using Git
include(FetchContent)

FetchContent_Declare(
    onnxruntime
    GIT_REPOSITORY https://github.com/microsoft/onnxruntime.git
    GIT_TAG v1.20.1  # Specify the desired version
)

# Fetch the content
FetchContent_MakeAvailable(onnxruntime)

# Add ONNX Runtime build
set(ONNX_RUNTIME_BUILD_SHARED_LIB OFF) # Use static linking for simplicity
set(ONNX_RUNTIME_BUILD_CSHARP OFF)
set(ONNX_RUNTIME_BUILD_PYTHON OFF)
set(ONNX_RUNTIME_BUILD_NODEJS OFF)
set(ONNX_RUNTIME_ENABLE_EXTENDED OFF)
set(ONNX_RUNTIME_USE_CUDA OFF)
set(ONNX_RUNTIME_USE_OPENVINO OFF)
set(ONNX_RUNTIME_BUILD_UNIT_TESTS OFF)

add_subdirectory(${onnxruntime_SOURCE_DIR}/cmake ${onnxruntime_BINARY_DIR})

# Add the executable for the minimal example
add_executable(mini_main src/main.cpp)

# Link ONNX Runtime to the executable
target_link_libraries(mini_main PRIVATE onnxruntime)

# Include ONNX Runtime headers
target_include_directories(mini_main PRIVATE ${onnxruntime_SOURCE_DIR}/include)

and here is the error.

...
CMake Error at build/_deps/onnxruntime-src/cmake/onnxruntime_mlas.cmake:746 (target_link_libraries):
  Target "onnxruntime_mlas_q4dq" links to:

    nsync::nsync_cpp

  but the target was not found.  Possible reasons include:

    * There is a typo in the target name.
    * A find_package call is missing for an IMPORTED target.
    * An ALIAS target is missing.

Call Stack (most recent call first):

Maybe some could help me.

Already there is an issue #12081

Next cmake code works, but not everytime
