Configure failure on CMake 3.29

[ziplantil]

What happened?

Project fails to configure on cmake version 3.29.0. There seems to be a problem with CMakeLists.txt; copying the cmake_minimum_required and cmake_policy directives to the CMakeLists.txt files in the subdirectories gets a bit further, but there are more issues later on as well (but out of scope for this issue).

Deleting build/ does not fix the issue.

CMake Warning (dev) in 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.

CMake Warning (dev) in CMakeLists.txt:
  cmake_minimum_required() should be called prior to this top-level project()
  call.  Please see the cmake-commands(7) manual for usage documentation of
  both commands.

Use -S . instead of -S src/.

Yeah, that solves it. It seems I got confused when reading the documentation. Thanks
