  I am running 3.10.2 at Bionic Beaver 18.04.5 and suffering from the following known issue: https://gitlab.kitware.com/cmake/cmake/-/issues/17954
  Unfortunately, the issue was fixed only in 3.12 and 3.10.2 is still affected.
  
  Can we please have the following patch back-ported for 18.04.5 updates
  https://gitlab.kitware.com/cmake/cmake/-/commit/ac5731a7e380349f19dc319e6c31e189b5faba93
  
  I've checked that the patch can be applied clearly on top of the 3.10.2,
  it is simple and self-consistent, so I don't expect that it will break
  something else.
  
  I've also verified that the patch indeed fixes the issue for me. Since
  the patch affects only CMake module and don't requires cmake rebuild it
  was simple enough.
