cmake warning

[ghost]

Using cmake version 3.0.2 (mkdir build; cd build ; cmake ../)
I get a warning that test/CMakeLists.txt line 15 is using the target name "test" which is now reserved or not valid for certain CMake features, such as generator expressions, and may result in undefined behavior.
This warning is for project developers. Use -Wno-dev to suppress it.

I can use cmake -Wno-dev ../ and ignore it, but I thought I'd let you know.
