[Buildroot] [PATCH v2] qt5wayland: compositor depends on qt5base opengl

[Joshua Henderson]

When building Qt 5.6.3, the qt5wayland compositor depends on Qt OpenGL support.
The compositor API is marked experimental prior to Qt 5.8.  In the latest
version of Qt this dependendency on opengl is removed.

This also removes the qt5wayland dependency on GL support, because this is tied
to the compositor API through the BR2_PACKAGE_QT5BASE_OPENGL dependency.

Fixes:

v2:
- Due to the compositor API being experimental in Qt 5.6.3, it does not make
  sense to address this dependency on OpenGL upstream in this version of Qt.
- Remove explicit dependency on GL support.
- Note that the compositor API is marked as stable starting with Qt 5.8 in help.
- Update commit message.

?Since it is no longer experimental in 5.11, and we assume most people will be
using the latest version, we can remove the (experimental) bit.


> +	depends on BR2_PACKAGE_QT5BASE_OPENGL || BR2_PACKAGE_QT5_VERSION_LATEST

?Wouldn't it make more sense to select opengl? Like:

??? depends on BR2_PACKAGE_QT5_GL_AVAILABLE || BR2_PACKAGE_QT5_VERSION_LATEST

??? select BR2_PACKAGE_QT5BASE_OPENGL if !BR2_PACKAGE_QT5_VERSION_LATEST


?Also, you need to keep the comment that was there originally, but now apply it
to the compositor rather than qt5wayland as a whole. And it should only be shown
for 5.6.


?Regards,
?Arnout
