I suggest you drop all mention of DESTDIR within cmake or trying anything
special to beat the system.  Instead work on getting a normal install to
work properly. My experience with cmake is that once the normal "make
install" works properly, then

make install DESTDIR='/temporary/staging/area'

works fine as well.
