For system libraries like this it is often better to just link them in 
with -l.  The compiler should be able to find them if it is installed 
correctly.  There is a good chance CMake will get it wrong.   So, the 
correct CMake solution for system/compiler libraries is to just use the 
name of the library.

Something like this:

if(MINGW)
target_link_libraries(foo uuid ole32 shell32)
endif(MINGW)
