无法在 VS 2019 上以发布模式为 SDL 库构建解决方案

Question

我试图从这个特定链接https://www.youtube.com/watch?v=PTQkCRxr6lk&t=194s下载 SDL 库。但是我偶然发现了一个“致命错误”，我不知道该怎么做才能解决它。

这是我得到的错误：

1>------ Build started: Project: SDL2, Configuration: Release x64 ------
2>------ Skipped Build: Project: uninstall, Configuration: Release x64 ------
2>Project not selected to build for this solution configuration

@Neri-kun 我在 VS2019 上构建 SDL2 时遇到了完全相同的问题。似乎memset是在vcruntime.dll，不包括在CMakeLists.txt. 所以找到以下部分CMakeLists.txt并添加vcruntime到EXTRA_LIBS. 问题解决了：

   # Libraries for Win32 native and MinGW
-  list(APPEND EXTRA_LIBS user32 gdi32 winmm imm32 ole32 oleaut32 version uuid advapi32 shell32)
+  list(APPEND EXTRA_LIBS vcruntime user32 gdi32 winmm imm32 ole32 oleaut32 version uuid advapi32 shell32)
