dnl @* AX_PATH_LIB_PCRE [(A/NA)]
|
|
dnl
|
|
dnl check for pcre lib and set PCRE_LIBS and PCRE_CFLAGS accordingly.
|
|
dnl
|
|
dnl also provide --with-pcre option that may point to the $prefix of
|
|
dnl the pcre installation - the macro will check $pcre/include and
|
|
dnl $pcre/lib to contain the necessary files.
|
|
dnl
|
|
dnl the usual two ACTION-IF-FOUND / ACTION-IF-NOT-FOUND are supported
|
|
dnl and they can take advantage of the LIBS/CFLAGS additions.
