依赖关系图表
在编译 PHP 时，每个扩展、库都有依赖关系，这些依赖关系可能是必需的，也可能是可选的。在编译 PHP 时，可以选择是否包含这些可选的依赖关系。
例如，在 Linux 下编译 gd 扩展时，会强制编译 zlib,libpng 库和 zlib 扩展，而 libavif,libwebp,libjpeg,freetype 库都是可选的库，默认不会编译，除非通过 --with-libs=avif,webp,jpeg,freetype 选项指定。
- 对于可选扩展（扩展的可选特性），需手动在编译时指定，例如启用 Redis 的 igbinary 支持：
bin/spc build redis,igbinary。 - 对于可选库，需通过
--with-libs=XXX选项编译指定。 - 如果想启用所有的可选扩展，可以使用
bin/spc build redis --with-suggested-exts参数。 - 如果想启用所有的可选库，可以使用
--with-suggested-libs参数。
