Question

在 cmake 找到 libpng 之后

将 PNG_INCLUDE_DIRS 定义为路径列表，但我不能只使用 include_directories（）来包含它方法（找不到 png.h ）

find_package(PNG REQUIRED)

message("include dirs: " ${PNG_INCLUDE_DIRS})
include_directories(${PNG_INCLUDE_DIRS})

foreach(include_dir ${PNG_INCLUDE_DIRS})
    message("in loop: " ${include_dir})
    include_directories(${include_dir})
endforeach(include_dir)

它产生输出：

include dirs: /usr/local/include/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/usr/include
in loop: /usr/local/include
in loop: /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/usr/include

有趣的是，如果我添加这一行

include_directories("/usr/local/include")

然后标题可见。看起来像cmake中列表的一些棘手的东西。我在OSX 10.11上使用CLion

png混乱的find_package包括dirs
