No, this is the solution, unless you want to build in a chroot'ed build root. 
In the environment where you're going to build a given software, you must not 
have the development packages of that software already installed.

That's also why I highly recommend against using any Linux distribution that 
lacks the concept of development package.

You must install and uninstall the development packages as needed then. Or set 
up a build root for building one or the other software. Or for both.

You probably have either -L/usr/lib or -L/usr/lib64 added to your linker line. 
Find the source of that option (probably a pkg-config file for GStreamer) and fix 
there.

If the issue is not a system path, then you've got the corner I mentioned. 
Unsolvable short of removing files.
