-# Static IDL files / Generated IDL files
-#
-# In GYP, paths needed to be passed separately for static and generated files, as
-# static files are listed in a temporary file (b/c too long for command line),
-# but generated files must be passed at the command line, as their paths are
-# not fixed at GYP time, when the temporary file is generated, because their
-# paths depend on the build directory, which varies.
-#
-# FIXME: GN does not have this restriction and we can combine them.
