Here you are doing exactly the opposite of what your commit log says:
you are installing from /usr/qml/QtQuick/Entreprise/VirtualKeyboard for
the latest Qt 5.11 version, and from /usr/qml/QtQuick/VirtualKeyboard
for the older Qt 5.6 version.

This also doesn't match the build failure: the build failure happens
with qt5virtualkeyboard 2.0, which is used with Qt 5.6, and your patch
proposes to use exactly the same command for the old Qt as the one that
is unconditionally used today.

I.e:

> +else
> +define QT5VIRTUALKEYBOARD_INSTALL_TARGET_QML
> +	cp -dpfr $(STAGING_DIR)/usr/qml/QtQuick/VirtualKeyboard $(TARGET_DIR)/usr/qml/QtQuick
> +endef

is exactly the same as:

> -	cp -dpfr $(STAGING_DIR)/usr/qml/QtQuick/VirtualKeyboard $(TARGET_DIR)/usr/qml/QtQuick

So I guess your condition is inverted, and the patch was not
sufficiently tested ? :-)

Thanks!
