MeshLib could not be built in the ubuntu24 container

[andrewerf]

I tried to build MeshLib in the provided environment, and it didn't work.

Steps to reproduce

1. git clone --recurse-submodules https://github.com/MeshInspector/MeshLib.git
2. docker build . -f docker/ubuntu24Dockerfile -t meshlib
3. docker run --rm -it meshlib and then cd ~/ && git clone --recurse-submodules https://github.com/MeshInspector/MeshLib.git && cd MeshLib
4. The following step produces an error:

user@c0b13035bfd1:~/MeshLib$ ./scripts/build_source.sh
Project build script started.
You could find output in /home/user/MeshLib/build_source_22-07-2024_19:01:50.log

  --help-policy CMP0146" for policy details.  Use the cmake_policy command to
  set the policy and suppress this warning.

This warning is for project developers.  Use -Wno-dev to suppress it.

CMake Error at /usr/share/cmake-3.28/Modules/FindPackageHandleStandardArgs.cmake:230 (message):
  Could NOT find CUDA: Found unsuitable version ".", but required is at least
  "12" (found /usr/local/cuda/)
Call Stack (most recent call first):

  /usr/share/cmake-3.28/Modules/FindCUDA.cmake:1291 (find_package_handle_standard_args)
  source/MRCuda/CMakeLists.txt:16 (find_package)

5. Even if I try to turn the CUDA off, it still doesn't work, building with the following command gives the same error

user@c0b13035bfd1:~/MeshLib$ export MR_CMAKE_OPTIONS="-DCMAKE_POLICY_DEFAULT_CMP0146=OLD -DMESHINSPECTOR_CUDA_SUPPORT=OFF"

As for ubuntu22, an undocumented hack is required to build the library in the container (I found it in the definition of the GitHub actions workflow):

$ ln -s /usr/local/lib/meshlib-thirdparty-lib/lib ./lib
$ ln -s /usr/local/lib/meshlib-thirdparty-lib/include ./include

should be invoked in the root of the repo. Otherwise, some dependencies are not found.
