lightvgl-sys 9.4.5

# 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.

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 = "." }
```

Alternatively, it can be added before cargo commands:

```sh
DEP_LV_CONFIG_PATH=`pwd` cargo build
```

## Optional configuration

You might as well need to set one or more of these env variables, especially when cross-compiling:
- `BINDGEN_EXTRA_CLANG_ARGS`: Extra clang arguments to be passed to bindgen
- `LV_COMPILE_ARGS`:  Extra arguments to be passed both to bindgen and to the C compiler
- `CROSS_COMPILE`: Target triple when cross-compiling
- `LIBCLANG_PATH`: Custom *libclang.so* location
