you should list this file path above. by convention targets should include files
for all platforms, then exclude them when they need to be excluded. this keeps
all the files visible in each platform's IDE. also in this case, you wouldn't
need to exclude it since the path includes chromeos, which means that the
filename filters should automatically do this

Done.
