dnl Look for a program to use as VARIABLE. If --with-VARIABLE is given, then
|
|
dnl set VARIABLE to the path provided there (WITH-ARG and HELP-STRING are
|
|
dnl used for --help output). Otherwise, set VARIABLE to the first of
|
|
dnl PROGS-TO-CHECK-FOR on the path; if none of those is found, leave
|
|
dnl VARIABLE unchanged.
|
|
dnl If the program was found, define HAVE_WITH-ARG.
