1.16 Uninstalled fails issue with LIBORC

Good Afternoon,

UPDATE: I can confirm that this issue is not present if I use MASTER version. git clone https://github.com/GStreamer/gst-build.git

I am working with Gst 1.16 git clone --branch 1.16.2 https://github.com/GStreamer/gst-build.git

I followed the guide and everything looks Ok until the uninstalled environment is launched.

Here < localroute > is a way to hide my local path

$ ninja -C build/ uninstalled 
ninja: Entering directory `build/'

I am in a fresh Ubuntu 18.04 x64 machine with all the LIBAV, LIBORC, PYTHON, and GSTREAMER devs dependencies already installed.

Meson version 0.54.2. From $ pip3 install --user meson

Ninja version 1.8.2. From repository Ubuntu 18.04

In fact, meson build/ and ninja -C build steps works. Here the exit from meson build/ which as far as I understand looks ok:

All GStreamer modules 1.16.2

                      tinyalsa: NO Subproject directory not found and tinyalsa.wrap file not found

Some hint about how to fix it?

I do not understand why these /usr/local/lib paths are defined because Host dependencies (no liborc subproject) is installed from repository at /usr/lib/

I would bet for an issue of Meson version and GST-BUILD 1.16 version. But, how to fix it?

Best,

Angel.
