-# We want to produce both a static and a shared libdawn_native library. The static one is for
-# unittests that need access to all the symbols of the library. The shared one is for the other
-# users that access libdawn_native through the regular interface.
-# We use a CMake "OBJECT" library type which allows precompiling the source files and reusing
-# them for both the static and the shared library. Recent CMake versions make it so if you
-# depend on an OBJECT library you get its dependencies and source files, which is very similar to
-# GN's source_set. However the versions of CMake on our test bots is too old and doesn't support
-# this, so instead we duplicate the deps everywhere.
