Support CMake 4.0

[LecrisUT]

We recently tried to naively update this package's support for CMake 4.0, but it seems there is some additional changes necessary based on the failure

--   Found zlib, version 1.3.1.zlib-ng
LIB3MF_TESTS ... ON
-- Configuring done (0.9s)
CMake Error at Tests/CPP_Bindings/CMakeLists.txt:51 (add_dependencies):
  The dependency target "crypto" of target "Test_CPP_Bindings" does not
  exist.


CMake Error at Tests/CPP_Bindings/CMakeLists.txt:50 (add_dependencies):
  The dependency target "ssl" of target "Test_CPP_Bindings" does not exist.

At first glance this is an issue with the visibility of the targets. There is a policy that fixes this issue which I can find for reference at a later time. Adding a higher bound to cmake_minimum_required might fix this issue.

Feel free to get in touch if you need help fixing this issue

@LecrisUT If you are integrating lib3mf into your project, you can disable tests for now.

-DLIB3MF_TESTS=off

This is in the context of Fedora packaging. Disabling tests is highly undesired. As mentioned we can help investigate and fix this issue. I already have clues of what is going wrong, but right now I am crunching to get CMake 4.x into Fedora, so cannot help until next week.

@LecrisUT I am the package maintainer. I will take a look at the issue this weekend.
