|
||||
* SDL2 (see below)
|
||||
|
||||
Aside from standard search options (`ZLIB_INCLUDE_DIR`, `ZLIB_LIBRARY`, ...) the following options are available:
|
||||
* `BUILD_SHARED_LIBS` (default: `ON`) - Build IrrlichtMt as a shared library
|
||||
* `BUILD_EXAMPLES` (default: `OFF`) - Build example applications
|
||||
* `ENABLE_OPENGL` - Enable OpenGL driver
|
||||
* `ENABLE_OPENGL3` (default: `OFF`) - Enable OpenGL 3+ driver
|
||||
* `ENABLE_GLES1` - Enable OpenGL ES driver, legacy
|
||||
* `ENABLE_GLES2` - Enable OpenGL ES 2+ driver
|
||||
* `USE_SDL2` (default: platform-dependent, usually `ON`) - Use SDL2 instead of older native device code
|
||||
|
||||
e.g. on a Linux system you might want to build for local use like this:
|
||||
|
||||
git clone https://github.com/minetest/irrlicht
|
||||
cd irrlicht
|
||||
cmake . -DBUILD_SHARED_LIBS=OFF
|
||||
make -j$(nproc)
|
||||
|
||||
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.
|
||||
|
||||
on Windows system:
|
||||
|
||||
It is highly recommended to use vcpkg as package manager.
|
||||
|
||||
After you successfully built vcpkg you can easily install the required libraries:
|
||||
|
||||
vcpkg install zlib libjpeg-turbo libpng sdl2 --triplet x64-windows
|
||||
|
||||
Run the following script in PowerShell:
|
||||
|
||||
git clone https://github.com/minetest/irrlicht
|
||||
cd irrlicht
|
||||
cmake -B build -G "Visual Studio 17 2022" -A "Win64" -DCMAKE_TOOLCHAIN_FILE=[vcpkg-root]/scripts/buildsystems/vcpkg.cmake -DBUILD_SHARED_LIBS=OFF
|
||||
cmake --build build --config Release
|
||||
However, IrrlichtMt cannot be built or installed separately.
