Do you mean DESTDIR?

DESTDIR is a Makefile convention supported by many Makefiles and by
newer (IIRC, >= 1.5) versions of automake.

Applying DESTDIR is simple, you can find examples on using it in many


Given an arbitrary package w/ DESTDIR support:

./configure --prefix=/somewhere

make DESTDIR=/tmp install

The last line will install the package to '/tmp' instead of '/', i.e.
the files normally installed to /somewhere will be copied/installed to

Inside of rpm.specs, the standard usage would be:

./configure --prefix=/somewhere
make DESTDIR=${RPM_BUILD_ROOT} install

rpm then will collect the files from below ${RPM_BUILD_ROOT}.

Check out scripts/cpukit, it contains a rough rpm.spec-skeleton of what you want.
