The already added "cmake_policy(SET CMP0079 NEW)" needs to be moved tot he top
of the file to take EXPAT into account as well to workaround this problem.
Though, the already mentioned problem with "log4cxx.rc" comes up again:

I couldn't find how I worked around that in the past... :-/
There are additional warnings I can't remember of in the past:

No cmake_minimum_required command is present. A line of code such as
cmake_minimum_required(VERSION 3.18)
should be added at the top of the file. The version specified may be lower
if you wish to support older CMake versions for this project. For more
information run "cmake --help-policy CMP0000".This warning is for project
developers. Use -Wno-dev to suppress it.

C:\Users\tschoening\Documents\Svn\Src\Libs\trunk\C++\Logging\log4cxx\master\src\src\CMakeLists.txt:
No project() command is present. The top-level CMakeLists.txt file must
contain a literal, direct call to the project() command. Add a line of code
such as
project(ProjectName)
near the top of the file, but after cmake_minimum_required().
CMake is pretending there is a "project(Project)" command on the first
line.This warning is for project developers. Use -Wno-dev to suppress it.

ALIAS or IMPORTED target. Run "cmake --help-policy CMP0028" for policy
details. Use the cmake_policy command to set the policy and suppress this
warning.
Target "log4cxx" links to target "EXPAT::EXPAT" but the target was not
found. Perhaps a find_package() call is missing for an IMPORTED target, or an
ALIAS target is missing?This warning is for project developers. Use -Wno-dev
to suppress it.

A private source from a directory other than that of target "log4cxx" has a
relative path.This warning is for project developers. Use -Wno-dev to suppress
it.

> I just tested building log4cxx using CMAKE and Visual Studio 2019 Community.
> Things failed and I want to use this bug to document everything that I've
> found, because for some things I'm not sure how to handle them properly. Will
> create a new branch to maintain the fixes I came along, so that those can at
> best be later reviewed by others. The branch of interest is currently named
> "logcxx_510_cmake_vs2019_compat".
