Building different versions of gstreamer

[Andrea Marson]

Hi,
I'm working with gstreamer on a PC running Ubuntu 18.04.
For my project, I need to build different versions of gstreamer along with
its plugins.
For instance, I recently built tag 1.16.2. After that, I needed to build
tag 1.14.4. However, building of gst-plugins-base 1.14.4 failed:

linking of temporary binary failed: Command '['../../../libtool',

I suspect this is due to the fact that I did not uninstall gstreamer
cleanly before building tag 1.14.4.
How to cleanly uninstall tag 1.16.2, which I installed by issuing "sudo
make install"?

Thank you in advance for you help.
