CMake Error at C:/vcpkg/installed/x64-windows/share/imgui-sfml/ImGui-SFMLConfig.cmake:63 (set_target_properties):
  The link interface of target "ImGui-SFML::ImGui-SFML" contains:

    OpenGL::GL

  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):
  C:/vcpkg/scripts/buildsystems/vcpkg.cmake:859 (_find_package)
