FetchContent compatibility?

[panpawel88]

Hello,

I wanted to add Realsense library as a dependency to my project. Realsense library is added by FetchContent cmake feature. However cmake generation fails on my side.

Here is my simple CMakeLists.txt file:

cmake_minimum_required(VERSION 3.28)
project(realsense_test)

include(FetchContent)

FetchContent_Declare(
        librealsense
        GIT_REPOSITORY "https://github.com/IntelRealSense/librealsense"
        GIT_TAG "8dab5816bef30d56bc185c21132892fe41fbc146"
)

FetchContent_MakeAvailable(librealsense)

set(CMAKE_CXX_STANDARD 17)

add_executable(realsense_test main.cpp)
target_link_libraries(realsense_test librealsense)

Error log:

// ...
CMake Error at cmake-build-debug/_deps/librealsense-src/tools/CMakeLists.txt:28 (include):
  include could not find requested file:

    /home/pawel/CLionProjects/realsense-test/CMake/opengl_config.cmake
// ...

Correct path for opengl_config.cmake is /home/pawel/CLionProjects/realsense-test/cmake-build-debug/_deps/librealsense-src/CMake/opengl_config.cmake.

Is Realsense library compatible with FetchContent? In https://github.com/IntelRealSense/librealsense/issues/12150 somebody wanted to clone with FetchContent, so I would expect that it should be working.

Hi @panpawel88 Installing RealSense with FetchContent is also discussed at the link below.

In their solution they fetch realsense2 instead of librealsense.

Hi @panpawel88 Do you require further assistance with this case, please? Thanks!

Hello @MartyG-RealSense ,

I couldn't get it working by FetchContent, but I've added realsense dependency by using vcpkg. My issue is solved.

Thanks
