This is modelled on the autoconf AC_SEARCH_LIBS. I guess the assumption is that you know which additional libs may be needed. If not, there is no alternative but to try various combinations of extra libs until it works. The foreach approach you have used seems like a reasonable way to do this. PS I see the you didn't commit autosetup/local.tcl (attached) You will want to do this to preserve drh's change to disable the pager.
