[CMake] Running library tests under MSVC2010

Yes. Everything works OK now. My question was more of a theoretical 
interest...

The reason why I expected it to "just work" under MSVC is that when 
working with MSVC without CMake, creating a dependency in test on the 
library makes test automatically load the library even though it is not 
on the system path. I have no idea how it works, I would expect MSVC IDE 
simply to add relevant library to the path when running the test.

Anyway, with CMake-generated solution this doesn't seem to work. The 
dependency is generated as expected, however, when trying to run the 
test MSVC is unable to find the library.
