Hi!

While working on the “reproducible builds” effort [1], we have noticed
that opencv's core module embeds the build path multiple times. It also
embeds the running kernel version and a build timestamp. The generated
Doxygen documentation also embeds the build path in multiple places.

I have opened a merge request on Salsa [2] to fix the above issues. Once
applied, it can be built reproducibly in our current experimental
framework.

Regards,

Victor Westerhuis
