比如这个文件jconfig.h.in

/* Version ID for the JPEG library.
 * Might be useful for tests like "#if JPEG_LIB_VERSION >= 60".
 */
#define JPEG_LIB_VERSION  @JPEG_LIB_VERSION@

/* This version of libjpeg-turbo supports run-time selection of data precision,
 * so BITS_IN_JSAMPLE is no longer used to specify the data precision at build
 * time.  However, some downstream software expects the macro to be defined.
 * Since 12-bit data precision is an opt-in feature that requires explicitly
 * calling 12-bit-specific libjpeg API functions and using 12-bit-specific data
 * types, the unmodified portion of the libjpeg API still behaves as if it were
 * built for 8-bit precision, and JSAMPLE is still literally an 8-bit data
 * type.  Thus, it is correct to define BITS_IN_JSAMPLE to 8 here.

zig怎么转换。

可以参考下这个 cpython 的构建方式
