Direzione di ricerca

Reproduce the warnings with the provided Ubuntu 24.04 Dockerfile, then read the CMake configuration and the named warning locations, including lib/ZenKit/vendor/libsquish/CMakeLists.txt and lib/bullet3/CMakeLists.txt. The issue lists several warnings across build configuration and third-party code but does not specify which should be addressed; clarify the intended scope before treating the warnings as resolved.

Descrizione

Hi, when building this natively I got several warnings. Not sure if these are already known from before, but I could not find any issues that listed these so...

CMake configuration warnings

When running cmake -B build -DBUILD_SHARED_LIBS=ON -DCMAKE_BUILD_TYPE:STRING=RelWithDebInfo
I got the following warnings:

CMake Warning (dev) at lib/ZenKit/vendor/libsquish/CMakeLists.txt:21 (OPTION):
  Policy CMP0077 is not set: option() honors normal variables.  Run "cmake
  --help-policy CMP0077" for policy details.  Use the cmake_policy command to
  set the policy and suppress this warning.

  For compatibility with older versions of CMake, option is clearing the
  normal variable 'BUILD_SHARED_LIBS'.
This warning is for project developers.  Use -Wno-dev to suppress it.

[...]

CMake Warning (dev) at /usr/share/cmake-3.28/Modules/FindOpenGL.cmake:381 (message):
  Policy CMP0072 is not set: FindOpenGL prefers GLVND by default when
  available.  Run "cmake --help-policy CMP0072" for policy details.  Use the
  cmake_policy command to set the policy and suppress this warning.

  FindOpenGL found both a legacy GL library:

    OPENGL_gl_LIBRARY: /usr/lib/x86_64-linux-gnu/libGL.so

  and GLVND libraries for OpenGL and GLX:

    OPENGL_opengl_LIBRARY: /usr/lib/x86_64-linux-gnu/libOpenGL.so
    OPENGL_glx_LIBRARY: /usr/lib/x86_64-linux-gnu/libGLX.so

  OpenGL_GL_PREFERENCE has not been set to "GLVND" or "LEGACY", so for
  compatibility with CMake 3.10 and below the legacy GL library will be used.
Call Stack (most recent call first):
  lib/bullet3/CMakeLists.txt:312 (FIND_PACKAGE)
This warning is for project developers.  Use -Wno-dev to suppress it.

Build warnings

When building with cmake --build ./build --target Gothic2Notr I get these warnings:

etc, there are quite a few warnings printed.
