4 The Irrlicht Engine is an open source realtime 3D engine written in C++.
6 This is a fork by the [Minetest](https://github.com/minetest) developers that was stripped-down and customized specifically for use in Minetest.
7 It is intentionally not compatible to upstream and is planned to be eventually absorbed into Minetest.
12 The build system is CMake.
14 The following libraries are required to be installed:
15 * zlib, libPNG, libJPEG
17 * or on mobile: OpenGL ES (can be optionally enabled on desktop too)
20 Aside from standard search options (`ZLIB_INCLUDE_DIR`, `ZLIB_LIBRARY`, ...) the following options are available:
21 * `BUILD_SHARED_LIBS` (default: `ON`) - Build IrrlichtMt as a shared library
22 * `BUILD_EXAMPLES` (default: `OFF`) - Build example applications
24 e.g. on a Linux system you might want to build for local use like this:
26 git clone https://github.com/minetest/irrlicht
28 cmake . -DBUILD_SHARED_LIBS=OFF
31 This will put an IrrlichtMtTargets.cmake file into the cmake directory in the current build directory, and it can then be imported from another project by pointing `find_package()` to the build directory, or by setting the `CMAKE_PREFIX_PATH` variable to that same path.
36 We aim to support these platforms:
42 This doesn't mean other platforms don't work or won't be supported, if you find something that doesn't work contributions are welcome.
47 The license of the Irrlicht Engine is based on the zlib/libpng license and applies to this fork, too.
