In your list of sources you specify "test", not "test.cxx".  The first 
time CMake can't find "test" so it automatically searches and finds 
"test.cxx".  Then when you do an in-source build there is now a file 
called test so CMake uses the executable itself as the source file. 
This is why the file type is wrong and why you get the circular 
dependency.  Just use

SET(TEST_SRCS test.cxx)
