Test per-config OUTPUT_DIRECTORY properties

We test (ARCHIVE|LIBRARY|RUNTIME)_OUTPUT_DIRECTORY_<CONFIG> properties
by building COnly as a subdirectory and setting the properties to put
its files in specific locations.  We build an executable that verifies
the targets actually appear where expected.
