PPA failures on Ubuntu 16.04

General Development

Has been happening for a couple days:

CMake Error at cMake/FindOpenCasCade.cmake:42 (list):
  list does not recognize sub-command FILTER
Call Stack (most recent call first):
  cMake/FreeCAD_Helpers/SetupOpenCasCade.cmake:4 (find_package)
  CMakeLists.txt:52 (SetupOpenCasCade)

CMake 3.5 doesn’t offer the FILTER option:
https://cmake.org/cmake/help/v3.5/command/list.html

But CMake 3.6 does:

I recently have used it to fix some very annoying compiler warnings as OCCT 7.5 adds some preprocessor defines that cause hundreds of compiler warnings with Qt5.x: 8ca1d2b3d441

I will have a look how to make it working again for 16.04.

With the 16.04 EOL coming on April 30th 2021 that should help avoid these sorts of problems for a while…
