The simple solution is: set PREFIX within the INSTALL(CODE) and that's it:

  install (CODE "include(DeployQt4)
                 set (PREFIX 
\$ENV{DESTDIR}\${CMAKE_INSTALL_PREFIX}/${CMAKE_INSTALL_BINDIR})
                 FIXUP_QT4_EXECUTABLE (\"\${PREFIX}/${ARGV0}.exe\"
                                       \"${PLUGINS}\"
                                       \"\"
                                       \"\${PREFIX}\"
                                       \"\${PREFIX}/plugins\")")

Note the additional '\' to evaluate the PREFIX variable at runtime, not 
configure time. Meh.
