Question

我正在运行Windows，我想在一个地方安装SDL开发文件，以便find_package（SDL）正常工作。

我应该在PATH中包含部分内容还是什么？

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" ..

我在维基页面上读了一下，发现了一个小小的解决方法。我不认为它很完美，但现在还不错。

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

这正确地找到了SDL2，虽然我遇到了另一个问题，但我会为它制作一个新主题。

检查应该找到您的包的CMace模块的文档和来源

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
