reassign 1020779 libcereal-dev 1.3.2+dfsg-2
thanks

From the build log in [1], it looks like the build error is:

CMake Warning at cmake/modules/Findcereal.cmake:6 (find_package):
  Could not find a configuration file for package "cereal" that is compatible
  with requested version "".

  The following configuration files were considered but not accepted:

/usr/share/cmake/cereal/cerealConfig.cmake, version: 1.3.2 (64bit)

Call Stack (most recent call first):
  CMakeLists.txt:448 (find_package)

I think this is because
/usr/share/cmake/cereal/cerealConfigVersion.cmake is not actually
architecture-dependent despite being shipped in an arch:all package 
(libcereal-dev).

Do you have a bit more context for this?

From the log, I can't see what the actual issue is.
Is it an autoconf check that fails or an actual compilation issue?

If it's a check, which one?

If it's actually in the source, the error doesn't make any sense. 
Compilation is done without -Werror, and the deprecation message is only 
a warning.
