我的环境正在使用CLion，运行CMake和Mingw。
我需要在我的项目中使用zlib，但我不能在我的生活中让它在windows中链接。
如果我按照this stackoverflow article的解决方案，尝试使用上述文章中的确切cmakelists构建zlib示例二进制文件，则会收到错误：
Could NOT find ZLIB (missing: ZLIB_INCLUDE_DIR)
我也无法在官方zlib网站上找到zlib的预编译二进制文件，zlib自己的文档说明应该存在于网站上，所以试图将其链接到我的项目上很困难。
我确实找到了一些二进制文件，但在尝试链接它们时，（我还在试图弄清楚如何将dll与cmake链接起来，这可能是问题的一部分），make系统只是nopes进行。
mingw32-make.exe[1]: *** [CMakeFiles/CMinecraft.dir/rule] Error 2
mingw32-make.exe: *** [CMinecraft] Error 2
CMakeFiles\Makefile2:153: recipe for target 'CMakeFiles/CMinecraft.dir/rule' failed
答案 0 :(得分：0)
Personnaly for windows（VS 2015/2017，但应该与Mingw合作）我将它作为CMake子项目集成使用：

我最终找到了解决办法。
CMake不知道在哪里找到zlib，即使它在当前的工作目录中。幸运的是，MinGW将它作为二进制文件的一部分，它可以被指向和使用。
set(ZLIB_INCLUDE_DIR "C:/MinGW/bin")
find_package(ZLIB REQUIRED)

include_directories(${ZLIB_INCLUDE_DIRS})
