I think you want to use DESTDIR if you are testing things after installing 
them.

There is a layer of testing that we can't do in a normal environment.  The 
problem is that the previously installed libraries provide backup that we 
don't want.  This is a variant on the problem of using the wrong libraries 
when testing pre-install.

We could fix that by adding a version check when loading libraries.  That 
version would have to include the time stamp rather than just a version number.

We could also try uninstalling the old stuff, but then we would have to debug 
and maintain that.

You want to test before install.  It would also be good to test post install, 
but that gets complicated if you have installed into DESTDIR rather than the 
normal working place.

I think the gitlab tests run in an environment without anything pre-installed. 
 Does that do any post-install testing?
