## Usage
Edit your `Cargo.toml` file dependencies with:
```
$ cargo add lvgl
```
The build requires the environment variable bellow to be set:
- `DEP_LV_CONFIG_PATH` : Path to the directory containing the `lv_conf.h` header file used for configuration of LittlevGL library.
We recommend the `lv_conf.h` file to be in your project's root directory. If so, the command to build your project would be:
```shell script
$ DEP_LV_CONFIG_PATH=`pwd` cargo build
```
