How to disable building glbinding::glbinding-aux?

[alphahex99]

In my root CMakeLists.txt I:

# glbinding
set(OPTION_BUILD_TOOLS OFF CACHE BOOL "" FORCE)
set(OPTION_BUILD_EXAMPLES OFF CACHE BOOL "" FORCE)
add_subdirectory(external/glbinding/)

And then I only link:

target_link_libraries(${PROJECT_NAME} PRIVATE
    glbinding::glbinding
    glfw
)

(note the missing glbinding::glbinding-aux linking)

But it seems like I'm missing an option or something and the glbinding-aux lib still gets built anyway just from adding this repo as a subdirectory:

and it takes soooooo long to build. I'd prefer not to.

Is there just an option similar to OPTION_BUILD_TOOLS / OPTION_BUILD_EXAMPLES to disable building it? Could it be added? Thanks.
