Question

我正在使用CMake构建一些应根据ScriptingBridge编译的代码。

我看到了成千上万的日志行，例如：

In file included from /Developer/SDKs/MacOSX10.7.sdk/System/Library/Frameworks/Security.framework/Headers/cssmapple.h:30,
                 from /Developer/SDKs/MacOSX10.7.sdk/System/Library/Frameworks/Security.framework/Headers/Security.h:25,

正在编译文件：

/usr/bin/c++    -I/Users/codebeaker/Projects/watchedit-client-code/src/libwhatsplaying/include -I/Users/codebeaker/Projects/watchedit-client-code/src/libwhatsplaying/../libwatchedit/include    -x objective-c -o CMakeFiles/whatsplaying.dir/src/osx/itunes_scripting_bridge.m.o -c /Users/codebeaker/Projects/watchedit-client-code/src/libwhatsplaying/src/osx/itunes_scripting_bridge.m

/usr/bin/gcc -I/Users/codebeaker/Projects/watchedit-client-code/src/libwhatsplaying/include -I/Users/codebeaker/Projects/watchedit-client-code/src/libwhatsplaying/../libwatchedit/include    -F/Developer/SDKs/MacOSX10.7.sdk/System/Library/Frameworks  -x objective-c -o CMakeFiles/whatsplaying.dir/src/osx/itunes_scripting_bridge.m.o -c /Users/codebeaker/Projects/watchedit-client-code/src/libwhatsplaying/src/osx/itunes_scripting_bridge.m

在我的Mac上查看了（Clang）gcc的手册页后，听起来很有趣：

-Fdir
Add the framework directory dir to the head of the list of directories to be searched for header files. These directories are interleaved with those
specified by -I options and are scanned in a left-to-right order.

A framework directory is a directory with frameworks in it. A framework is a directory with a "Headers" and/or "PrivateHeaders" directory contained
directly in it that ends in ".framework". The name of a framework is the name of this directory excluding the ".framework". Headers associated with
the framework are found in one of those two directories, with "Headers" being searched first. A subframework is a framework directory that is in a
framework's "Frameworks" directory. Includes of subframework headers can only appear in a header of a framework that contains the subframework, or in
a sibling subframework header. Two subframeworks are siblings if they occur in the same framework. A subframework should not have the same name as a
framework, a warning will be issued if this is violated. Currently a subframework cannot have subframeworks, in the future, the mechanism may be
extended to support this. The standard frameworks can be found in "/System/Library/Frameworks" and "/Library/Frameworks". An example include looks
like "#include ", where Framework denotes the name of the framework and header.h is found in the "PrivateHeaders" or "Headers"
directory.

-iframeworkdir
Like -F except the directory is a treated as a system directory. The main effect is to not warn about constructs contained within header files found
via dir.

也许我应该寻找-iframework。在终端上使用-iframework构建时，手动完成时不会发生任何弃用警告。

但是，CMake不支持使用-framework的选项。来自他们的find_library()文档：

CMake将使用-framework A和-F将框架链接到目标。

我正在寻找一种安静的构建方式。我还有（4x）来自OpenSSL'x EVA界面的小警告，我可以处理的......提前感谢。

答案是使用-iframework，可能是因为当您无法解决时忽略系统级别的弃用警告。

相反，我能够使用-Wno-deprecated-declarations，GCC的一个标记，记录在案，并随处可用。它是可靠的，我把它包含在我的CMake声明中：

IF(${CMAKE_SYSTEM_NAME} MATCHES "Darwin")
  find_and_add_framework(Foundation watchedit)
  find_and_add_framework(Cocoa watchedit)
  find_and_add_framework(AppKit watchedit)
  find_and_add_framework(ScriptingBridge watchedit)
  set_source_files_properties(${sources} PROPERTIES COMPILE_FLAGS
    "-xobjective-c -Wno-deprecated-declarations")
  set_source_files_properties(${sources} PROPERTIES LANGUAGE C)
ENDIF(${CMAKE_SYSTEM_NAME} MATCHES "Darwin")

对于任何有益的人，这里是find_and_add_framework的实施。我不知道我从哪里弄它，但这不是我自己的工作：

macro(FIND_AND_ADD_FRAMEWORK fwname appname)
    find_library(FRAMEWORK_${fwname}
        NAMES ${fwname}
        PATHS ${CMAKE_OSX_SYSROOT}/System/Library
        PATH_SUFFIXES Frameworks
        NO_DEFAULT_PATH)
    if( ${FRAMEWORK_${fwname}} STREQUAL FRAMEWORK_${fwname}-NOTFOUND)
        MESSAGE(ERROR ": Framework ${fwname} not found")
    else()
        TARGET_LINK_LIBRARIES(${appname} ${FRAMEWORK_${fwname}})
        # MESSAGE(STATUS "Framework ${fwname} found at ${FRAMEWORK_${fwname}}")
    endif()
endmacro(FIND_AND_ADD_FRAMEWORK)

OSX弃用警告CMake
