This adds documentation on the environment variables needed to the message telling that no conversion support is compiled in. Committer testing: $ make -C tools/perf install $ perf data convert --all --to-ctf myctftrace No conversion support compiled in. perf should be compiled with environment variables LIBBABELTRACE=1 and LIBBABELTRACE_DIR=/path/to/libbabeltrace/ $ Signed-off-by: Geneviève Bastien <gbastien@versatic.net> Acked-by: Jiri Olsa <jolsa@kernel.org> Tested-by: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Francis Deslauriers <francis.deslauriers@efficios.com> Cc: Julien Desfossez <jdesfossez@efficios.com> Cc: Mathieu Desnoyers <mathieu.desnoyers@efficios.com> Cc: Peter Zijlstra <peterz@infradead.org> Link: http://lkml.kernel.org/r/20170727181205.24843-3-gbastien@versatic.net Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
