 # Static IDL files / Generated IDL files

 # In GYP, paths need 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. While GYP
 # is still supported, we match its behavior for easier maintenance but this can
 # be simplified.
