I suppose HAVE_DEF_MAKE_UNIQUE should have been set to one but it wasn't. Removing HAVE_DEF_MAKE_UNIQUE from cmake's cache didn't help.The check_cxx_source_compiles() in ConfigureChecks.cmake was never executed and HAVE_DEF_MAKE_UNIQUE was never set.
In the end I started from scratch and then the check ran and HAVE_DEF_MAKE_UNIQUE=1.
