HEre, you said "with specific EGL wayland extensions", so...

... should not that be also depend on BR2_PACKAGE_HAS_LIBEGL_WAYLAND ?

Note that BR2_PACKAGE_HAS_LIBEGL_WAYLAND is a sub-option of
BR2_PACKAGE_HAS_LIBEGL, so both should be added as dependency, but...

... indeed only libegl needs to be added to _DEPENDENCIES.
