Whenever possible, you should use absolute paths to libraries.

CMP0015 actually does not change this.
The only thing it does, is that if you use a relative path, e.g. "mylibs/", 
then with CMP0015 set to OLD, this will be interpreted as 
${CMAKE_CURRENT_BINARY_DIR}/mylibs/, while with CMOP0015 set to NEW, it will 
be interpreted as ${CMAKE_CURRENT_SOURCE_DIR}/mylibs/
