Dirk, Brett, do you know if I need any rebase_path magic here? The
third_party/angle/BUILD.gn file I looked (among others), does some, hence I'm
not sure if I need one here or not.

[Dirk Pranke, 2015/03/30 20:38:21]

I'm not sure. Brett?

[brettw, 2015/03/30 21:00:26]

That depends on what the files in the gypi are relative to.

GN will treat them as being relative to the current directory. GYP treats them
as being relative to the .gyp file that includes the .gypi. If these don't
match, you need to rebase_path to get from the GYP path to the GN one.

[tfarina, 2015/03/30 21:03:39]

So, since both gles2_conform_test.gyp and BUILD.gn are on the same directory, we
are fine?

Do'h, no, actually you were talking about the source files. They are in
third_party/gles2_conform/GTF_ES/...
