Correct.  The new modular build system uses modern CMake conventions.
The use of LIBRARY_OUTPUT_PATH has been superseded by the
(RUNTIME|ARCHIVE|LIBRARY)_OUTPUT_DIRECTORY properties which allow each
type of file to be located separately.  Since we set all three for
targets at the top then all three need to be changed for a specific
target if all .lib, .a, .dll, and .so files are to be affected.

However, for a plugin CMake prefers the use of MODULE rather than SHARED
libraries.  Then only LIBRARY_OUTPUT_DIRECTORY would need to be set.  I
don't remember why ITK uses SHARED rather than MODULE for its plugins.
