gst-build 1.14 on Ubuntu 16.04 isn't working for me

Sat Aug 11 00:26:31 UTC 2018

I tried to build gstreamer using gst-build on the 1.14 branch on Ubuntu
16.04 using the command: *meson build && ninja -C build/*

The full output is pasted at the end of this email, but to summarize I got
this error:

Dependency libffi not found but it is available in a sub-subproject.
To use it in the current project, promote it by going in the project source
root and issuing the following command.

meson wrap promote subprojects/glib/subprojects/libffi.wrap
||Couldn't use fallback subproject in subprojects/libffi for the dependency
libffi
||Reason: Subproject directory 'subprojects/libffi' does not exist and
cannot be downloaded:
||No libffi.wrap found for 'subprojects/libffi'
|Couldn't use fallback subproject in subprojects/glib for the dependency
glib-2.0
|Reason: subprojects/glib/meson.build:1551: Native dependency 'libffi' not
found

subprojects/gstreamer/meson.build:386:0: ERROR:  Native dependency
'glib-2.0' not found

Next I tried to follow the given suggestion but no luck:

ing at ing-ub01:~/dev/github/gstreamer/gst-build$ *meson wrap promote
subprojects/glib/subprojects/libffi.wrap*
Subproject libffi.wrap not found in directory tree.

I also tried `sudo apt-get install libffi-dev` but it didn't help either.

How can I make the build work?
