I get errors (although now at least it says '17' instead of '20' so that's progress):

  CMake Error at src/CMakeLists.txt:113 (add_executable):
    CXX_STANDARD is set to invalid value '17'
  
  
  CMake Error at src/frontends/CMakeLists.txt:18 (add_library):
    CXX_STANDARD is set to invalid value '17'
  
  
  CMake Error at src/frontends/qt/CMakeLists.txt:42 (add_library):
    CXX_STANDARD is set to invalid value '17'
  
  
  CMake Error at src/frontends/tests/CMakeLists.txt:10 (add_executable):
    CXX_STANDARD is set to invalid value '17':

g++ --version
g++ (Ubuntu 5.4.0-6ubuntu1~16.04.12) 5.4.0 20160609

I don't use this system much so if that GCC version is too old, then I'm
fine if we do not support it. But if we dream that someday Pavel will
switch to CMake, we should be ready :)
