Probe Item

A Probe item can appear inside a Product Item and is run prior to building products in order to locate dependent headers, libraries, and other files outside the project directory whose locations are not known ahead of time. Probes are similar to configure scripts.

Note: Because Probes often invoke external processes, which is relatively expensive compared to evaluating normal properties, their results are cached. To force re-evaluation of a Probe, you can supply the --force-probe-execution command-line option.
