Problem to build mfx gstreamer plugins

[jbolduc01]

I have an UpSquared board using latest Ubuntu 18.04 and I have some problems to build it.
Linux up 5.3.0-42-generic #34~18.04.1-Ubuntu SMP Fri Feb 28 13:42:26 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux
When I do cmake ..

-- MediaSDK distribution found in /opt/intel/mediasdk
-- MediaSDK include directory: /opt/intel/mediasdk/include
-- MediaSDK library directory: /opt/intel/mediasdk/lib/lin_x64/libmfx.a
Build: release
-- Configuring done
-- Generating done
-- Build files have been written to: /home/up/gstreamer-media-SDK/build

When I try make, I have the following output:

[  1%] Building C object CMakeFiles/gstmfx.dir/gst/mfx/gstmfx.c.o

It seems there is an issue similar to this actually but it does help.
Do you know what this could be?

I tried to do
export PKG_CONFIG_PATH=/opt/intel/mediasdk/lib/pkgconfig/
and then cmake .. & make
Here is what I get after make:
[ 1%] Built target gstmfx
Result of sudo make install:

[100%] Built target gstmfx
Install the project...
-- Install configuration: "release"
-- Installing: /usr/local/gstreamer-1.0/libgstmfx.so
-- Set runtime path of "/usr/local/gstreamer-1.0/libgstmfx.so" to "/opt/intel/mediasdk/lib"

using gst-inspect-1.0:

up@up:~/gstreamer-media-SDK/build$ gst-inspect-1.0 mfxvpp
No such element or plugin 'mfxvpp'

Any ideas?

can you try the topic_linux_and_window branch instead?
