The test needs to be able to load the test_ce library at run-time.
If you didn't explicitely disable it, cmake builds the executables by default
with the complete RPATH to all used libraries (the "build RPATH").
This is replaced during make install by the "install RPATH", which is by
default empty.
So it should actually just work.

The tests are not being linked to the library. The tests are dlopening them
at run time.
