Why would that be needed? Kconfig 'depends' is transitive. That is, since 
glmark2 depends on glmark2-gl/glmark2-egl-gles, that in turn depend on mesa3d, 
glmark2 automatically also depends on mesa3d dependencies. It is only for 
'select' that we need to manually propagate dependencies.

Did you hit any specific problem?
