skia2/third_party/expat/BUILD.gn
Mike Klein 10d665d000 Allow most third_party targets to use system libraries if asked.
This extends the pattern in freetype2 to expat, icu, libjpeg-turbo, libpng, libwebp, and zlib, and gives all these an arg to control which to use.

Homebrew doesn't have dng_sdk, piex, or sftnly, or I'd have done the same for them too.
