lttng-tools-2.14.0-rc1: Not possible to disable babeltrace2 dependency

[Norbert Lange via lttng-dev]

Hello,

I had to add babeltrace2_CFLAGS="-DA" babeltrace2_LIBS="-lm" to the
configure line
to be able to build.

There should be a --without-babeltrace2 switch and possible automatic detection.

Regards, Norbert

Hi Norbert,

could you describe more about the context of the system you were 
building on, and which version of babeltrace you had installed?

thanks,
kienan

Its a crosstool-ng toolchain based on gcc 10.5.
There is NO babeltrace2 available, and that is what is not handled, I
have to define babeltrace2_CFLAGS and babeltrace2_LIBS to make it
through the checks.

Hi Norbert,

thanks for the reporting this issue! I've proposed a patch[1] to handle 
the case you've described.

thanks,
