[raylib] Undifined Reference to asan / ubsan

[AregevDev]

Describe the bug Hello, I am trying to install and use raylib port, which depends on glfw. I have a simple CMake project. It seems like the GLFW port requires the adress sanitizer runtime. When adding asan and ubsan to my target_link_library, my program compiles and runs but reports false (?) memory leaks from glfw3. My intention is to completely disable the address sanitizer runtime.

I tried manually building glfw3 from source and it doesn't happen.

Environment

• OS: EndevourOS KDE Plasma
• Compiler: GCC 14.1.1

To Reproduce Steps to reproduce the behavior:

1. Download the example project
2. Run vcpkg install
3. Build with CMake

Expected behavior A clear and concise description of what you expected to happen.

Failure logs cmake_error.txt

Confirmed that the issue has been reproduced locally.

You can solve your problem by adding the following two sentences in cmakelists.txt. You also need to install asan and ubsan on your Linux.

target_compile_options(raylib_text PRIVATE -fsanitize=address -fsanitize=undefined)
target_link_options(raylib_text PRIVATE -fsanitize=address -fsanitize=undefined)

This DOES NOT solve the problem.

• The request is to DISABLE sanitizers, not to enable them.
• AFAICT vcpkg's raylib is meant to use vcpkg's port glfw (note ports/raylib/fix-linkGlfw.patch, but the error message points at a vendored copy:

  /home/oak/Documents/vcpkg/buildtrees/raylib/src/5.0-9a639cbe9d.clean/src/external/glfw/src/init.c:97:(.text+0xfb): undefined reference to `__ubsan_handle_pointer_overflow'`

• raylib's portfiles enables sanitizers for debug build. IMO it shouldn't.

Oh, so the problem in the raylib port, interesting. I'll try using GLFW alone to confirm it. Maybe I'll submit a PR to disable asan in the vcpkg port...

Maybe add the option to use the GLFW port instead of the vendored GLFW as well.

I tried to come up with a PR. It seems like enabling sanitizers is done in the toolchain settings, not in port features. There is zero documentation about it. I am not even sure where the ENABLE_ASAN and ENABLE_UBSAN flags come from.

Please change the issue title: The offending port is raylib, not glfw.
