In the cmake FAQ, it indicates that cmake will use the DESTDIR on the

What is the level of precedence for this variable setting, with regard to
cache values that are set at the time of cmake configuration (using
-Dvar:type=val)? That is, if cmake is called with something like
-DCMAKE_INSTALL_PREFIX:PATH=${prefix}, will 'gmake install
DESTDIR=${anotherPrefix}' use the cache variable setting for ${prefix} or
will it use the command line setting for ${anotherPrefix} when setting
rpath in dynamic libs.
Furthermore, what is the relationship between these variable settings for
the install path and, on OSX, the setting for CMAKE_INSTALL_NAME_DIR? Does
this variable interact in any way with the DESTDIR command line setting
(for dynamic library builds)?
The DESTDIR env.variable is a purely install-time thing, i.e. it doesn't
affect CMAKE_INSTALL_PREFIX or RPATH or install_name_dir.
E.g. if you set CMAKE_INSTALL_PREFIX to /home/alex/install, and then before do
install like this:
$ DESTDIR=/tmp/blub/ make install
then everything will be installed into /tmp/blub/home/alex/install
