1466328 - Allow compiling without gtk2

Status: RESOLVED DUPLICATE of bug 1377445

(Core :: Widget: Gtk, defect)

Description

[Hussam Al-Tayeb]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:60.0) Gecko/20100101 Firefox/60.0
Build ID: 20180601164825

Steps to reproduce:

While firefox does not use gtk2 themeing anymore and uses gtk3 instead, it still requires gtk2 at compile time. this is likely for flash plugin?

Otherwise I get the following build error:

Expected results:

Allow compiling without gtk2.
