Update build system to CMake 4

[carlos-h-h]

CMake was installed with scoop. I don't know if it's relevant, but since the guide said to "Add CMake to the system PATH for all users", I'll mention that ...\scoop\shims (location of cmake.exe) is both in my user's and the system path.

PS ~\dev\ext\nappgui_src> cmake -S . -B build
CMake Deprecation Warning at CMakeLists.txt:9 (cmake_minimum_required):
  Compatibility with CMake < 3.10 will be removed from a future version of
  CMake.

  Update the VERSION argument <min> value.  Or, use the <min>...<max> syntax
  to tell CMake that the project requires at least <min> but has been updated
  to work with policies introduced by <max> or earlier.

Hi @carlos-h-h! Thanks for use NAppGUI. Please use a cmake version < 4.0 (3.29.3 is working in my Windows CI nodes). Still I have not tested NAppGUI build system for CMake > 4

If problem persist, please go to /build/tools/build and open NAppGUITools.sln with VS. Try to compile and share the build logs.

Worked perfect with cmake 3.31.7. Thanks 👍

(Maybe add the needed cmake version to the documentation, the default is 4.0.2 now.)

I'm experiencing similar issue on MSYS2. But MSYS2 is a rolling release system, it's unable for me to roll back to previous CMake version.
