If you look in config.status you will see the form that the cached
values take. You can then unset the cache variable that autoconf uses
before trying again. Here is some example code taken from one of my
configure scripts:
have_libdps='no'
LIBDPS_XT=''
AC_CHECK_LIB(dps,DPSInitialize,have_libdps='yes',have_libdps='no',)
if test "$have_libdps" != 'yes'
then
# Unset cache variable so we can try again.
unset ac_cv_lib_dps_DPSInitialize
AC_CHECK_LIB(dps,DPSInitialize,have_libdps='yes',have_libdps='no',-lXt)
if test "$have_libdps" = 'yes'
then
LIBDPS_XT='-lXt'
