Suddenly not finding Boost.Format dependency?

[jzmaddock]

Starting some time in the last 24 hours many of the Boost.Math CI tests are failing due to a missing boost/format.hpp, see for example: https://github.com/boostorg/math/actions/runs/6768902679/job/18401577644?pr=1046

The annoying thing is I see no changes in Math, Boostdep, or Format that would cause this!

Hoping you have more ideas than I do...

And yes, this is a bit of a release blocker for us :(

Refs boostorg/math#1046.

You need to tell depinst to look into tools for dependencies because

https://github.com/boostorg/math/blob/11e2348372088f0ede36ff6cbf2d70c8e1783a3b/test/Jamfile.v2#L1678

boost/format.hpp is only included from sources in tools.

The reason this worked before is that Boost.Format was a (false) dependency of PropertyTree, and I removed it.

While there, you should also fix it to look in example as well, for the same reason. Do that by adding -I example -I tools to the depinst invocation here:
