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.

mingw32 / mingw64 cmake can also just straight up run out of memory when building it, I had to switch to ucrt64:

cc1plus.exe: out of memory allocating 528383 bytes
mingw32-make[2]: *** [external\glbinding\source\glbinding-aux\CMakeFiles\glbinding-aux.dir\build.make:274: external/glbinding/source/glbinding-aux/CMakeFiles/glbinding-aux.dir/source/Meta_StringsByEnum.cpp.obj] Error 1
mingw32-make[1]: *** [CMakeFiles\Makefile2:541: external/glbinding/source/glbinding-aux/CMakeFiles/glbinding-aux.dir/all] Error 2
mingw32-make: *** [Makefile:145: all] Error 2

glbinding already takes a long time to build and I timed how much glbinding-aux adds on my PC - it's like an extra 4 minutes.

Thanks for reporting your use case.
As we have options to disable other optional targets within the glbinding project, it comes natural to have one for glbinding-aux, too. I can add such an option.

In the meantime, it might be worth selecting only the glbinding target when building the project:

> cmake --build build --target glbinding

(or the corresponding build-tool-specific variant).
This approach wouldn't help with the install target, though...

Thank you!😄 I really need to get a new computer.😵‍💫

It's so useful for learning and figuring things out to have a minimal version that takes less time to build when I'm messing with my CMake build scripts and have to constantly keep rebuilding, which can take a lot of time on old HW.🙂
