Clownacy ac465d29b4 Mean CMake dependency overhaul

I'm taking a page from Dolphin's book, and including copies of each
dependency's source code. This combines the ease of use of including
pre-built libraries instead of needing to navigate a package manager
 - as is (or was) the case for MSVC - with the portability of using
packages. Granted, this method's more of a jack of all trades,
master of none, since it's *less* user-friendly than prebuilt
packages (compilation times), and you don't get the per-distro
compatibility fixes you'd get from a package manager.

You can still use system libs if you want. In fact, it's still the
default behaviour: compiling the libs manually is just a fallback.
I'll add an option to force-enable this soon, however, since it's a
nicer way to produce static MSYS2 builds than the hackish nightmare
that I was using before. Not to mention, having my own copy of the
sources means I can provide my own fixes and tweaks your package
manager may not. For example, I can combine MSYS2's FreeType
subpixel rendering with vcpkg's fix for SDL2 exporting its symbols
in static builds.

DirectFB

Supports:

Hardware YUV overlays
OpenGL - software only
2D/3D accelerations (depends on directfb driver)
multiple displays
windows

What you need:

DirectFB 1.0.1, 1.2.x, 1.3.0
Kernel-Framebuffer support: required: vesafb, radeonfb ....
Mesa 7.0.x - optional for OpenGL

/etc/directfbrc

This file should contain the following lines to make your joystick work and avoid crashes:

disable-module=joystick disable-module=cle266 disable-module=cyber5k no-linux-input-grab

To disable to use x11 backend when DISPLAY variable is found use

export SDL_DIRECTFB_X11_CHECK=0

To disable the use of linux input devices, i.e. multimice/multikeyboard support, use

export SDL_DIRECTFB_LINUX_INPUT=0

To use hardware accelerated YUV-overlays for YUV-textures, use:

export SDL_DIRECTFB_YUV_DIRECT=1

This is disabled by default. It will only support one YUV texture, namely the first. Every other YUV texture will be rendered in software.

In addition, you may use (directfb-1.2.x)

export SDL_DIRECTFB_YUV_UNDERLAY=1

to make the YUV texture an underlay. This will make the cursor to be shown.

Simple Window Manager

The driver has support for a very, very basic window manager you may want to use when running with "wm=default". Use

export SDL_DIRECTFB_WM=1

to enable basic window borders. In order to have the window title rendered, you need to have the following font installed:

/usr/share/fonts/truetype/freefont/FreeSans.ttf

OpenGL Support

The following instructions will give you software OpenGL. However this works at least on all directfb supported platforms.

As of this writing 20100802 you need to pull Mesa from git and do the following:

git clone git://anongit.freedesktop.org/git/mesa/mesa cd mesa git checkout 2c9fdaf7292423c157fc79b5ce43f0f199dd753a

Edit configs/linux-directfb so that the Directories-section looks like

Directories

SRC_DIRS = mesa glu GLU_DIRS = sgi DRIVER_DIRS = directfb PROGRAM_DIRS =

make linux-directfb make

echo Installing - please enter sudo pw.

sudo make install INSTALL_DIR=/usr/local/dfb_GL cd src/mesa/drivers/directfb make sudo make install INSTALL_DIR=/usr/local/dfb_GL

To run the SDL - testprograms:

export SDL_VIDEODRIVER=directfb export LD_LIBRARY_PATH=/usr/local/dfb_GL/lib export LD_PRELOAD=/usr/local/dfb_GL/libGL.so.7

./testgl
