如何安装 SDL 开发库以便 CMake 可以找到它

Question

我是运行 Windows，我想在一个地方安装 SDL 开发文件，以便 find_package(SDL) 工作。

我应该将它的一部分包含在 PATH 中还是什么？

编辑：我创建了环境变量 SDLDIR 并将其设置为包含 lib/ 和 include/

的目录

Cmake 输出：

cmake -G "Visual Studio 12 2013 Win64" ..

Answer 1

检查应该找到您的包的 CMace 模块的文档和源代码

FindSDL.cmake 包含以下文档注释：

# $SDLDIR is an environment variable that would correspond to the
# ./configure --prefix=$SDLDIR used in building SDL.  l.e.galup 9-20-02

我在 wiki 页面上阅读了一些内容，发现了一个小的解决方法。我不认为它是完美的，但现在还可以。

cmake -G "Visual Studio 12 2013 Win64" -D SDL_LIBRARY_TEMP=%SDLDIR%\lib\x64\SDL2.lib ..

这正确地找到了 SDL2，虽然我运行进入另一个问题，但我会为它创建一个新主题。
