Hi!
While working on the "reproducible builds" effort [1], we have noticed
that blender could not be built reproducibly.
Specifically, the current system time is used to define BUILD_DATE and
BUILD_TIME in build_files/cmake/buildinfo.cmake, obviously rendering
the build unreproducible.
The attached patch uses SOURCE_DATE_EPOCH [2] instead of the current
time. This should make the build reproducible.
Regards,
Fabian Wolff
