dnl Comments in this file start with the string 'dnl'.
dnl Remove where necessary. This file will not work
dnl without editing.

dnl If your extension references something external, use with:

PHP_ARG_WITH(opencv, for opencv support,
Make sure that the comment is aligned:
[  --with-opencv             Include opencv support])

dnl Otherwise use enable:

dnl PHP_ARG_ENABLE(opencv, whether to enable opencv support,
dnl Make sure that the comment is aligned:
dnl [  --enable-opencv           Enable opencv support])
