The LOCATION property is an old feature intended for refering to 
executables in custom commands (it is no longer needed because 
add_custom_command recognizes target names as COMMANDs):

http://www.cmake.org/cmake/help/cmake2.6docs.html#prop_tgt:LOCATION

It does not work with per-configuration library names or suffixes.

If you want to place the library in a custom location, look at these 
properties:

http://www.cmake.org/cmake/help/cmake2.6docs.html#prop_tgt:RUNTIME_OUTPUT_DIRECTORY
http://www.cmake.org/cmake/help/cmake2.6docs.html#prop_tgt:LIBRARY_OUTPUT_DIRECTORY
http://www.cmake.org/cmake/help/cmake2.6docs.html#prop_tgt:ARCHIVE_OUTPUT_DIRECTORY

or use the install() command.
