CMake Error: imgui-sfml broken build dependency (branch is missing?)

[binarycounter]

It seems like it is currently not possible to build the master branch for Linux because CMake fails to fetch this specific commit of your imgui-sfml fork.

-- Configuring incomplete, errors occurred!

I was able to fix this by manually downloading the zip for this specific commit, unzipping it and modifying CMakeLists.txt, like this:

if(NOT SSVOH_ANDROID)
    CPMAddPackage(
        NAME imgui-sfml
        SOURCE_DIR "/home/dev/imgui-sfml-f35f353376281c0a891a4d614a241914ddfcbe29"
        )

    set_target_properties(ImGui-SFML PROPERTIES UNITY_BUILD ON)
endif()
