[epiphany/gnome-3-26] Compile gsettings schemas in build directory

[Michael Catanzaro <mcatanzaro src gnome org>]

commit 965e04d4a2ca0836e6b2d5588118bc401d6dacde
Author: Michael Catanzaro <mcatanzaro igalia com>
Date:   Fri Mar 2 20:46:43 2018 -0600

    Compile gsettings schemas in build directory
    
    This allows us to run the tests in situations where Epiphany is not
    installed on the host system, e.g. when running under BuildStream.
    
    As a bonus, we'll point Epiphany here as well when built in developer
    mode, so that it can be run from the build directory when uninstalled.
    This is needed to facilitate easy build/test/run inside BuildStream.

+# We need three custom_target() calls because Meson doesn't have very
+# good support for GSettings yet. First, generate our GSettings enums
+# in the build directory. Then, copy the gschema into the build
+# directory to ensure it is in the same place as the enums file. Then
+# we can run glib-compile-schemas on it. We have to compile schemas in
+# the build directory to ensure that our tests don't fail if run on a
+# system where epiphany is not already installed. epiphany will also
+# look for schemas here if built in developer mode.
