### `bgfx_compile_texture`
Add a build rule for a texture to the generated build system be compiled using texturec.
```cmake
bgfx_compile_texture(
FILE filename
OUTPUT filename
[FORMAT format]
[QUALITY default|fastest|highest]
[MIPS]
[MIPSKIP N]
[NORMALMAP]
[EQUIRECT]
[STRIP]
[SDF]
[REF alpha]
[IQA]
[PMA]
[LINEAR]
[MAX max size]
[RADIANCE model]
[AS extension]
)
```
### `bgfx_compile_shader_to_header`
Add a build rule for a `*.sc` shader to the generated build system using shaderc.
