-Subject: [PATCH] Also link against libharfbuzz-subset when use_system_harfbuzz is true
-
-When building HarfBuzz as part of Chromium, there is a single source set
-with all the files we need in the build.
-
-Upstream HarfBuzz, on the other hand, produces a few different libraries:
-harfbuzz, harfbuzz-icu and harfbuzz-subset.  When |use_system_harfbuzz| is
-true, we were only looking for (and using) harfbuzz.pc with pkg-config even
-though we also use symbols from libharfbuzz-subset.so. This resulted in
-errors when linking:
