Summary:                    get_filename_component(ABSOLUTE) return wrong value
for parent dir of /
Description: 
On unix-like system the parent directory of / should be / itself. However,
get_filename_component return empty string for that case.


Steps to Reproduce: 
In (sh-compatible) command line, type:
cmake -DINPUT='/../lib' -P /dev/stdin <<EOF
get_filename_component(abspath "\${INPUT}" ABSOLUTE)
message("\${abspath}")
EOF

expected output /lib
actual output lib (which is not an absolute path at all !!)
