我使用CMake为Visual Studio生成了一个解决方案。它会像原始解决方案一样编译罚款。但是当我查看我的输出文件夹时，这些文件的大小与初始解决方案生成的文件大小不同。
示例：
初始解决方案产生的DLL：
core.dll - 767ko
通过CMake的解决方案生成相同的DLL：
core.dll - 669Ko
同样的事情出现在.lib上：
zlib.lib - 305 Ko（初始解决方案）
zlib.lib - 242 Ko（用于CMake解决方案）
但我使用Visual Studio 2013两个......而且类型是相同的：Debug / Win32。我多次验证所有Flags，但无论如何它仍会生成不同大小的文件。
编辑：我添加了我的CMakeLists

有没有人知道可能导致这种情况的原因？
