 I think I got it to work like this:

# This is a hack to avoid circular dependencies when selecting OPENSSL
config BR2_PACKAGE_QT5ENGINIO_SELECT_OPENSSL
	bool
	default y if BR2_PACKAGE_QT5ENGINIO
	select BR2_PACKAGE_OPENSSL

config BR2_PACKAGE_QT5ENGINIO
	bool "qt5enginio"
	depends on !BR2_PACKAGE_QT5_VERSION_5_6 || \
                (BR2_PACKAGE_QT5_VERSION_5_6 && \
                (!BR2_PACKAGE_OPENSSL_FORCE_LIBOPENSSL && \
                !(BR2_TOOLCHAIN_USES_UCLIBC && !BR2_USE_MMU)))
	select BR2_PACKAGE_QT5BASE_GUI
	select BR2_PACKAGE_QT5BASE_NETWORK


 Could you give that a go?

 Arnout
