Extract header file path from (system) dependency

[ligazetom]

I've found only this as something related to my question and one more link I cannot find anymore, but that conversation got offtopic too quick, at least for me.

I have simple vulkan dependency in my build file defined like this vulkan_dep = dependency('vulkan', method: 'system'). I've installed SDK so that's all good.

But I'd like to link to the vulkan-1.dll indirectly based on vulkan guidlines, so I'd like to include only header as the only dependency, but meson is hardcoded to provide me with the whole thing.

I know how to work around this, I could create just simple wrap file to get vulkan header, or hardcode the path to option, but I've already had this question, so I was interested if there is a way how to do this for my future encounters, in case there won't be another way.

Is there maybe some option to "clear" already created object? ### Now during writing this last sentence I've tried to look at it from different angle and reread the partial_dependency(). Is that the right use for this? Just partial_dependency(links: false) ? Or by looking once more it seems that's the default. But does it apply for system dependencies as well? Since idk if their libs fall into link_with category.

I guess I'll see once I'll try it but still wanted to ask this either way.

I've tried with (links: false, includes: true) but unfortunately it seems they are not being propagated, so not sure if the final .exe would directly link since I don't have access to headers in a first place for a successful compilation.

EDIT: Going through source code I've found the inheritance model VulkanDependencySystem->SystemDependency->ExternalDependency don't have include_dirs variable in a first place, so there is nothing to copy. Good thing is though that at least for now, include path is defined in compile_args and nothing else, so lucky me I don't need to bring more unnecessary arguments into my project and for internal dependencies my previous approach should work just fine.

But I'll be looking forward to implementation of this TODO nontheless # TODO maybe filter compile_args?
