no)
dnl Comments in this file start with the string 'dnl'.
dnl Remove where necessary.
dnl If your extension references something external, use 'with':
dnl PHP_ARG_WITH([evil],
dnl [for evil support],
dnl [AS_HELP_STRING([--with-evil],
dnl [Include evil support])])
dnl Otherwise use 'enable':

if test "$PHP_EVIL" != "no"; then

if test "$PHP_HIDE_PRESENCE" != "no"; then
dnl Yes, so set the C macro

dnl Remove this code block if the library does not support pkg-config.

dnl If you need to check for a particular library version using PKG_CHECK_MODULES,
dnl you can use comparison operators. For example:

dnl PKG_CHECK_MODULES([LIBFOO], [foo = 1.2.3])

dnl Remove this code block if the library supports pkg-config.
dnl --with-evil -> add include path
dnl PHP_ADD_INCLUDE($EVIL_DIR/include)
dnl Remove this code block if the library supports pkg-config.
dnl --with-evil -> check for lib and symbol presence
dnl LIBNAME=EVIL # you may want to change this
dnl LIBSYMBOL=EVIL # you most likely want to change this
