Both, but for different purpose.

CMAKE_INSTALL_PREFIX should be used to control install prefix at
**CONFIGURE time**
whereas
DESTDIR is an **INSTALL time**  mechanism.

so you can perfectly do:

cmake -DCMAKE_INSTALL_PREFIX=/usr/local
and
make install ---> install things under /usr/local

whereas
make DESTDIR=/home/vivek  install
--> install things under /home/vivek/usr/local
