You may not need the variables-in-variables hack for the libjpeg_turbo.

Well, you don’t need it in this particular changelist as it stands right now.
You should be able to get away with getting rid of the definition of
libjpeg_turbo above and just making this one 'libjpeg_turbo%': 0. However, if
you can successfully implement my other suggestion about putting a
libjpeg_gyp_path variable into this file, you most likely will need to keep this
variables-in-variables hack.

Thank you for your comment. As written here, I need a variables-in-variables
hack for 'libjpeg_gyp_path'. Therefore, I removed this "libjpeg_turbo" hack and
added a "libjpeg_gyp_path" back.
