Linking

If libwebp is found in the system, it links against the library. Otherwise it builds and links against the bundled libwebp.

In these cases, static link is preferred:

  • For musl target.
  • When cross-compiling.
  • static feature is turned on.
  • LIBWEBP_SYS_STATIC environment variable is set to 1 when building.
