# lightvgl-sys
Rust raw bindings for the LVGL C library.
## Usage
Build requires the following environment variables to be set:
- `DEP_LV_CONFIG_PATH`: Path to the directory containing the `lv_conf.h` header file used for configuration of the LVGL library.
- `LIBCLANG_PATH`: Can be set with `~/export-esp.sh` (or for desktop `sudo apt install clang` then `/usr/lib/llvm-<version>/lib`)
It is easier to store them in `.cargo/config.toml` then rust-analyzer will also pick them up.
```toml
[env]
DEP_LV_CONFIG_PATH = { relative = true, value = "." }
LIBCLANG_PATH = "..."
```
Alternatively, it can be added before cargo commands:
```sh
DEP_LV_CONFIG_PATH=`pwd` cargo build
```
