# SYNOPSIS
#
#   AX_WITH_APXS([value-if-not-found], [path])
#
# DESCRIPTION
#
#   Locates an installed apxs binary, placing the result in the precious
#   variable $APXS. Accepts a preset $APXS, then --with-apxs, and failing
#   that searches for apxs in the given path (which defaults to the system
#   path). If apxs is found, $APXS is set to the full path of the binary;
#   otherwise it is set to VALUE-IF-NOT-FOUND, which defaults to apxs.
#
#   Example:
#
#     AX_WITH_APXS(missing)
