Subject: [PATCH] configure.ac: add --disable-examples option to not
|
build/install examples
|
|
Some environments and distributions do not need the LTTng-UST examples
|
to be built because they remove them anyway. Continue to build them by
|
default, but add --disable-examples to explicitly disable them.
