cmake doesn't define args_INCLUDE_DIRS

[yurivict]

The gccdiag project uses args_INCLUDE_DIRS here.

However, args_INCLUDE_DIRS isn't defined after find_package(args REQUIRED).

Please consider adding the section "Using with cmake" to the README explaining how to use args.

When this is installed with CMake, the correct usage for this project is the target. You should be able to do this, I think, with target_link_libraries($projectname taywee::args).

You do make a good point. CMake build instructions should be included. I've added an example CMakeLists.txt to the examples directory and a note in the readme about this. If you've installed cmake in the expected way (cmake -s$argsdir -B$builddir && cmake --build $builddir && cmake --install $builddir, with any optionally replaced CMAKE_INSTALL_PREFIX), then this should work as expected.
