如何以编程方式迭代所有CMake目标？

Is there a way to get all targets of a CMake project from within the top level CMakeLists.txt, i.e. iterate over the targets programmatically?

有没有办法从*CMakeLists.txt中获取CMake项目的所有目标,即以编程方式迭代目标?

The reason I want to do this is to apply some XCode specific settings to every target . .

我想这样做的原因是将一些特定于XCode的设置应用于每个目标。。

if (CMAKE_GENERATOR MATCHES "Xcode")
    include(sanitize_xcode)
    sanitize_xcode(myTarget)
endif()

FYI - the sanitization module looks like this . .

仅供参考 - 消毒模块看起来像这样。。

macro (set_xcode_property TARGET XCODE_PROPERTY XCODE_VALUE)
    set_property (TARGET ${TARGET} PROPERTY XCODE_ATTRIBUTE_${XCODE_PROPERTY} ${XCODE_VALUE})
endmacro (set_xcode_property)

macro (sanitize_xcode TARGET)
    set_xcode_property(${TARGET} GCC_GENERATE_DEBUGGING_SYMBOLS[variant=Debug] "YES")
    set_xcode_property(${TARGET} GCC_GENERATE_DEBUGGING_SYMBOLS[variant=MinSizeRel] "NO")
    set_xcode_property(${TARGET} GCC_GENERATE_DEBUGGING_SYMBOLS[variant=RelWithDebInfo] "YES")
    set_xcode_property(${TARGET} GCC_GENERATE_DEBUGGING_SYMBOLS[variant=Release] "NO")

    set_xcode_property(${TARGET} COPY_PHASE_STRIP[variant=Debug] "NO")
    set_xcode_property(${TARGET} COPY_PHASE_STRIP[variant=MinSizeRel] "YES")
    set_xcode_property(${TARGET} COPY_PHASE_STRIP[variant=RelWithDebInfo] "NO")
    set_xcode_property(${TARGET} COPY_PHASE_STRIP[variant=Release] "YES")

    set_xcode_property(${TARGET} GCC_OPTIMIZATION_LEVEL[variant=Debug] "0")
    set_xcode_property(${TARGET} GCC_OPTIMIZATION_LEVEL[variant=MinSizeRel] "s")
    set_xcode_property(${TARGET} GCC_OPTIMIZATION_LEVEL[variant=RelWithDebInfo] "3")
    set_xcode_property(${TARGET} GCC_OPTIMIZATION_LEVEL[variant=Release] "3")

    set_xcode_property(${TARGET} IPHONEOS_DEPLOYMENT_TARGET[variant=Debug] "7.0")
    set_xcode_property(${TARGET} IPHONEOS_DEPLOYMENT_TARGET[variant=MinSizeRel] "7.0")
    set_xcode_property(${TARGET} IPHONEOS_DEPLOYMENT_TARGET[variant=RelWithDebInfo] "7.0")
    set_xcode_property(${TARGET} IPHONEOS_DEPLOYMENT_TARGET[variant=Release] "7.0")
endmacro (sanitize_xcode)

To have a list of all targets is a wish that has been out there for a while, but the global property TARGETS is not yet implemented (as for May-2016, see "Listing all targets" discussion).

获得所有目标的列表是一个已经存在一段时间的愿望,但全球属性TARGETS尚未实现(截至2016年5月,请参阅“列出所有目标”讨论)。

Edit: It is now implemented: Global BUILDSYSTEM_TARGETS property was released with CMake 3.7

编辑:现在实现:全局BUILDSYSTEM_TARGETS属性随CMake 3.7一起发布

So you can implement this yourself using CMake script itself - as @DevSolar as commented/answered or like here - but I've learned over the time working with CMake that you could also change a lot of target properties globally. E.g. most target properties are defaulted to an equivalent global variable setting.

所以你可以自己使用CMake脚本自己实现这个 - 就像@DevSolar一样评论/回答或者像这里一样 - 但是我已经学会了与CMake一起工作,你也可以在全球范围内改变很多目标属性。例如。大多数目标属性默认为等效的全局变量设置。

You can take advantage of this in your case and solve this by adding the following to your global CMakeLists.txt file:

您可以在您的情况下利用这一点,并通过将以下内容添加到您的全局CMakeLists.txt文件来解决此问题:

set(CMAKE_XCODE_ATTRIBUTE_GCC_GENERATE_DEBUGGING_SYMBOLS[variant=Debug] "YES")
set(CMAKE_XCODE_ATTRIBUTE_GCC_GENERATE_DEBUGGING_SYMBOLS[variant=MinSizeRel] "NO")
set(CMAKE_XCODE_ATTRIBUTE_GCC_GENERATE_DEBUGGING_SYMBOLS[variant=RelWithDebInfo] "YES")
set(CMAKE_XCODE_ATTRIBUTE_GCC_GENERATE_DEBUGGING_SYMBOLS[variant=Release] "NO")

set(CMAKE_XCODE_ATTRIBUTE_COPY_PHASE_STRIP[variant=Debug] "NO")
set(CMAKE_XCODE_ATTRIBUTE_COPY_PHASE_STRIP[variant=MinSizeRel] "YES")
set(CMAKE_XCODE_ATTRIBUTE_COPY_PHASE_STRIP[variant=RelWithDebInfo] "NO")
set(CMAKE_XCODE_ATTRIBUTE_COPY_PHASE_STRIP[variant=Release] "YES")

set(CMAKE_XCODE_ATTRIBUTE_GCC_OPTIMIZATION_LEVEL[variant=Debug] "0")
set(CMAKE_XCODE_ATTRIBUTE_GCC_OPTIMIZATION_LEVEL[variant=MinSizeRel] "s")
set(CMAKE_XCODE_ATTRIBUTE_GCC_OPTIMIZATION_LEVEL[variant=RelWithDebInfo] "3")
set(CMAKE_XCODE_ATTRIBUTE_GCC_OPTIMIZATION_LEVEL[variant=Release] "3")

set(CMAKE_XCODE_ATTRIBUTE_IPHONEOS_DEPLOYMENT_TARGET[variant=Debug] "7.0")
set(CMAKE_XCODE_ATTRIBUTE_IPHONEOS_DEPLOYMENT_TARGET[variant=MinSizeRel] "7.0")
set(CMAKE_XCODE_ATTRIBUTE_IPHONEOS_DEPLOYMENT_TARGET[variant=RelWithDebInfo] "7.0")
set(CMAKE_XCODE_ATTRIBUTE_IPHONEOS_DEPLOYMENT_TARGET[variant=Release] "7.0")

If you want to go over a list of targets, set your CMakeLists.txt up to provide that list in the first place.

如果要查看目标列表,请将CMakeLists.txt设置为首先提供该列表。

if ( CMAKE_GENERATOR MATCHES "Xcode" )
    include(sanitize_xcode)
endif()

# A list of executables to build
set( project_EXECUTABLES
     foo
     bar
   )

# List of sources for each executable, following some naming scheme

# foo
set( EXE_foo_SOURCES
     foo/main.c
   )

# bar
set( EXE_bar_SOURCES
     bar/main.c
   )

# For each executable in the list...
foreach( exe ${project_EXECUTABLES} )
    # declare the target...
    add_executable( ${exe} ${EXE_${exe}_SOURCES} )

    # ...and do whatever additional configuration you need
    if ( CMAKE_GENERATOR MATCHES "Xcode" )
        sanitize_xcode( ${exe} )
    endif()
endforeach()
