## How to Build
247-
To build native libraries you should install `mingw-w64` and `ant`. Modify [GenerateLibs](https://github.com/SpaiR/imgui-java/blob/master/buildSrc/src/main/groovy/imgui/generate/GenerateLibs.groovy)
248-
to build specific binaries you need. After you've configured everything, run `gradlew :imgui-binding:generateLibs`.
249-
That will build native libraries and place them in `imgui-binding/build/libsNative` folder.
247+
To build native libraries you need:
248+
- Unix-like system (MacOS to build natives for Mac)
249+
- Installed dependencies: `mingw-w64`, `ant`, `freetype2`
250+
251+
After you've configured everything, run `gradlew :imgui-binding:generateLibs -Denvs=${envShortcut} -Dlocal`.<br>
252+
`envShortcut` could be `win32`, `win64`, `linux32`, `linux64` or `mac64`.<br>
253+
`-Dlocal` is optional and means that natives will be built under the `./imgui-binding/build/` folder. Otherwise `/tmp/imgui` folder will be used.
