Fixes: get tests compiling again that depend on the cpp library

Details:  This gets the tests running again, by statically linking
them. qmake doesn't have support for depending upon other projects
being built, so when the projects are built out of order, libCPlusPlusTest.so
wasn't being built before trying to be linked against.
