Lazy_test points to shared libs when static libs are enforced #472

The following CMake file has a logic error:

https://github.com/stepcode/stepcode/blob/74b6fe45751bd60be749bc80766f38745d29ed72/src/cllazyfile/CMakeLists.txt

In the case of a build with shared_libs=off, lazy_test still points to the shared libraries.
