Bug#1006844: intel-mediasdk: reproducible builds: Embeds kernel version in various .so files

[Vagrant Cascadian]

Source: intel-mediasdk
Severity: normal
Tags: patch
User: reproducible-builds at lists.alioth.debian.org
Usertags: kernel
X-Debbugs-Cc: reproducible-bugs at lists.alioth.debian.org

various .so files embed the kernel version of the build machine:

│ │ │ ├── ./usr/lib/x86_64-linux-gnu/mfx/libmfx_vp8d_hw64.so
...
│ │ │ │ │ -mediasdk_build_info: Debian 5.10.0-11-amd64 | GNU 11.2.0 | glibc 2.33
│ │ │ │ │ +mediasdk_build_info: Debian 2.6.70-11-amd64 | GNU 11.2.0 | glibc 2.33

The attached patch fixes this by removing the use of
CMAKE_SYSTEM_VERSION, which includes the running kernel version.

This patch alone does not resolve all reproducibility issues (e.g. build
paths tested only on unstable/experimental), but with this patch
applied, intel-mediasdk should build reproducibly on
tests.reproducible-builds.org once it migrates to bookworm/testing!


Thanks for maintaining intel-mediasdk!


live well,
