configure and multiple threads

When I need to compile an application from sources (I'm talking in a linux environment) basically the procedure is the following:

Usually I pass -j4 to make in order to use all the CPU resources and speed up (a lot!) the compilation process.

I'm wondering if there is something similar for configure which often takes a lot of time for execution. Of course I've already tried to pass the same option but it fails, and I find nothing related in configure --help.

No, configure scripts generally do not conventionally allow for distributed or parallelized execution.

Results are usually cached in configure.cache so you might be able to refactor for parallel execution without too much effort.

If you want to save on running multiple configuration jobs for different libraries where they may run the same tests multiple times, have them share the same cache file. See https://www.gnu.org/software/autoconf/manual/autoconf-2.65/html_node/Cache-Files.html
