In fact, this is sort of what libvirt does.  We have a 'run.in' script
template at the top directory, then create 'run' in the build tree
(whether or not it is a VPATH tree); the run script then primes any
necessary environment variables to execute commands using the build tree
as its preferred location for executables, dynamic libraries, and helper
files.
