It is quite surprising that it needs libegl unconditionally, while
Wayland does not. But that's indeed what upstream requires, so...

I've use a "depends on BR2_PACKAGE_WAYLAND" instead, because it's
obvious if you want Wayland C++ bindings that you need to enable
wayland first. Thanks to this I've dropped the thread and !static
dependencies.

Applied to next with those changes. Thanks!
