Robert Middleton commented on LOGCXX-510:
-----------------------------------------
So after thinking about this for a bit, I think the following summarizes the
issue:
# In order for tests(and log4cxx in general) to run, APR and APR-Util DLLs
must be on your PATH or in the directory that the application starts from.
# The directories for APR and APR-Util are found using the FindAPR.cmake and
FindAPR-Util.cmake in src/cmake.
# With the default settings(as it does not find apr-config or apu-config
executables), this will only find the DLLs for APR and APR-util, but not expat
since that is a transitive dependency of log4cxx.
# It is possible that the apr-config and apu-config executables add the
correct flags to build on Windows. They do not on Linux, as this does not seem
to be a problem there.
# In order to run the tests, since we find the directories where the DLLs are,
we simply prepend those directories to our PATH before running the tests.
The possible solutions that I see are as follows:
# Provide a configuration option to allow the user to input a custom path that
will be prepended to the PATH before running the tests(this is likely needed
for the tests to work with zip/grep/sed anyway).
# Assume that all of the dependencies needed to build and run the tests are in
a common directory(this is how I run them, with the APR and expat DLLs
installed in the same directory).
# Depend on expat directly and get rid of the apr_xml_XXX family of methods(I
like this as I would like to replace as many uses of APR as possible with
standard C++ library calls).

> 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".
