Almost.
Since installing happens at buildtime (so depending projects can find their 
dependencies), it's more like:

$ export DESTDIR=/some/path    # <- must be absolute path
$ cmake -DCMAKE_SKIP_RPATH=TRUE .....     # DESTDIR must be also set at cmake
                  # time, so the dependencies are found in DESTDIR
                  # and RPATH has to be disabled completely, because I think
                  # there is no way to get a correct RPATH with using DESTDIR
$ make            # <- builds and installs into DESTDIR


And it will complain 
* if DESTDIR is set, but not an absolute path
* if it changes from cmake-time to build-time and later on
* if DESTDIR is set but RPATH is not disabled
