Ok, so there is probably no inherent problem, it's just that it happens
to not work. What I dislike a bit with such dependency is that you
probably don't have tested on the full range of architectures that are
supported in Buildroot. So I generally prefer when we add such
dependencies when the software can really technically not work on the
architecture, not when there is some random bug that prevents it.

But oh well, I won't oppose to this dependency being added.

The namespace of variables is global, so SSL is not a good variable
named, it should be TURBOLUA_SSL.

What about defining:

TURBOLUA_MAKE_OPTS = \
	$(TARGET_CONFIGURE_OPTS) \
	SSL=$(if $(BR2_PACKAGE_OPENSSL),openssl,none) \
	LUAJIT_VERSION="$(LUAJIT_VERSION)"

and use it in the build and install steps ?

Best regards,
