Only compile VirtualTerminal if libinput is found The implementation of VirtualTerminal is too linux specific and doesn't compile on e.g. freebsd. Currently the most usage is in combination with libinput. Only usage is: * libinput related functionality in InputRedirection * backends without custom input handling Thus binding the feature to whether libinput is available is currently the least invasive approach to get it compile on non-Linux. In the long run this needs a different solution. The functionality provided by VirtualTerminal is required and without the backends don't work. It's needed to get notified about VT switches, when KWin needs to stop rendering. So a solution for non-Linux needs to be found if non-Linux wants to provide Wayland in future.

Add a hwcomposer backend based on libhybris This backend interacts with libhybris to create a hwcomposer which is used for creating the egl context and surface. The initial version of this backend is based on test_hwcomposer.cpp provided by libhybris. Please note that using the hwcomposer backend requires a newer libepoxy, the latest stable release is not able to bring up OpenGLES, so one needs a master build of libepoxy. Notes on licensing: libhybris is Apache 2.0 licensed, which is not compatile with GPLv2. But it is compatible with GPLv3. Thus the source files in the hwcomposer backend are licensed GPLv3+ and not GPLv2+ as the rest of KWin. If one uses KWin without the hwcomposer backend (which is obviously the default) the licence doesn't change. But if the hwcomposer backend is used the overall license of KWin changes to GPLv3+. 2015-05-06 15:47:07 +00:00			`endif()`
[wayland] Add a virtual framebuffer backend A new backend which doesn't present the rendered output. It uses a QPainter scene, renders to a QImage but doesn't present it anywhere. Thus a real virtual backend. By exporting the environment variable KWIN_WAYLAND_VIRTUAL_SCREENSHOTS the backend creates a temporary dir, prints the path to std-out and saves each rendered frame into that directory. Of course with exit it will be deleted again. 2015-10-02 08:44:29 +00:00			`add_subdirectory(virtual)`
Create a plugin for each of the wayland backends Each of the backends becomes a plugin. This allows kwin_wayland to load the requested plugin and kwin itself doesn't need to link all the libraries needed. E.g. libdrm is no longer linked if running kwin_x11. Also this allows to create backends for the non-standard EGL platforms (examples could be raspberrypi or Android devices). 2015-05-05 15:58:09 +00:00			`add_subdirectory(wayland)`
Move the x11 plugin sources into a x11/windowed directory Preparation step for having two x11 backends: the windowed for Wayland and a standalone for kwin_x11. 2016-04-08 07:30:22 +00:00			`add_subdirectory(x11)`
