Bug#996551: llvm-13-dev: Missing dependency to libomp-13-dev

[Sylvain Joubert]

Package: llvm-13-dev
Version: 1:13.0.0-5
Severity: important
X-Debbugs-Cc: joubert.sy at gmail.com

Dear Maintainer,

With the recent move of llvm-omp-device-info from llvm-X to libomp8-dev, done
in llvm-toolchain-13 (1:13.0.0-4),
this package should now depend on libomp-X-dev

The current situation is that llvm-X-dev references llvm-omp-device-info as
part of an installed targets in its cmake
configuration, but since it no longer provides that file any attempt to use the
LLVM cmake package results in an error:

CMake Error at /usr/lib/llvm-13/lib/cmake/llvm/LLVMExports.cmake:1501
(message):
  The imported target "llvm-omp-device-info" references the file
     "/usr/lib/llvm-13/bin/llvm-omp-device-info"
  but this file does not exist.  Possible reasons include:
  * The file was deleted, renamed, or moved to another location.
  * An install or uninstall procedure did not complete successfully.
  * The installation package was faulty and contained
     "/usr/lib/llvm-13/lib/cmake/llvm/LLVMExports.cmake"
  but not all the files it references.

Manually installing libomp-X-dev fixes the problem.
