+Subject: [PATCH] Explicitly link against WSLAY when available
+
+When other libraries attempt to link against libh2o and libh2o-evloop that was
+compiled with libwslay available, there are errors from missing symbols
+associated with code which makes use of the wslay library. To rectify this,
+explicitly link against libwslay during the build process.
+
+Fixes #2105
