| 3 | dnl Provides --with-PACKAGE, --with-PACKAGE-include and --with-PACKAGE-libdir
|
|---|
| 4 | dnl options to configure. Supports the now standard --with-PACKAGE=DIR
|
|---|
| 5 | dnl approach where the package's include dir and lib dir are underneath DIR,
|
|---|
| 6 | dnl but also allows the include and lib directories to be specified seperately
|
|---|
| 7 | dnl
|
|---|
| 8 | dnl adds the extra -Ipath to CFLAGS if needed
|
|---|
| 9 | dnl adds extra -Lpath to LD_FLAGS if needed
|
|---|
| 10 | dnl searches for the FUNCTION in the LIBRARY with
|
|---|
| 11 | dnl AC_CHECK_LIBRARY and thus adds the lib to LIBS
|
|---|
| 12 | dnl
|
|---|
| 13 | dnl defines HAVE_PKG_PACKAGE if it is found, (where PACKAGE in the
|
|---|
| 14 | dnl HAVE_PKG_PACKAGE is replaced with the actual first parameter passed)
|
|---|
| 15 | dnl note that autoheader will complain of not having the HAVE_PKG_PACKAGE and you
|
|---|
| 16 | dnl will have to add it to acconfig.h manually
