OWL - Open Windowing Library

OWL (Open Windowing Library)

OWL is intended to be a simple multiplatform windowing library based on Wayland, Xlib and WinAPI (eventually with Cocoa support in the future).

The plan is for OWL to support Software, OpenGL and Vulkan graphics.

To build the library use either cmake or make:

cmake -B ./build
cmake --build ./build

or

make 

This will result in a libOWL.dll.a and libOWL.dll / OWL.lib and OWL.dll library files being created in the ./build/ directory. Additionally 3 examples (executables) will be compiled along with it.

To turn compiling examples off, set: BUILD_EXAMPLES to NO. For example like this:

cmake -B ./build -DBUILD_EXAMPLES=NO

or (with make)

make BE=NO

To compile as static library, set LIBTYPE to STATIC. For example like this:

cmake -B ./build -DLIBTYPE=STATIC

or (with make)

make LT=STATIC

owl's Issues

Wayland support.

Ignore hPrevInstance in WinAPI_Data

Commit: 6c4376b

hPrevInstance in WinMain always contains NULL starting with Windows 95, so there's no point in keeping it up. If you really need a previous instance, use CreateMutex as indicated in the documentation.
