[boost::unit_test] SDL_main build fail

[warsark]

Describe the bug VCPKG install with classic mode.

in my project not use any boost lib,and not include any boost header. when build,the compile show error, this project is a old project compile without vcpkg, use lib and include, When I remove the lib and use vcpkg compile this project, this error is occur. I create a new project,use old source file,but the error already exist.

Environment

• OS: Windows 11
• Compiler: VS2022 17.10.0

To Reproduce Steps to reproduce the behavior:

1. ./vcpkg install sdl2[alsa,vulkan]:x86-windows-static
2. ./vcpkg install glm:x86-windows-static
3. ./vcpkg install sdl2[alsa,vulkan]:x86-windows-static

I delete all file and code only keep this code: int SDL_main(int argc, char* argv[]) { return 0; } the error alweays exists!!! change SDL_main to main the program run!!!

I found console project change main to SDL_main the project compile error! Repro code when
