如何以编程方式遍历所有CMake目标? [英] How do I iterate over all CMake targets programmatically?

问题描述

是否有办法从顶层CMakeLists.txt内获取CMake项目的所有目标，即以编程方式遍历目标?

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?

我要执行此操作的原因是将某些XCode特定的设置应用于每个目标. .

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

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

FYI-清理模块如下所示. .

FYI - the sanitization module looks like this . .

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)

将我的评论变成答案

拥有所有目标的列表已经存在了一段时间，但尚未实现全局属性TARGETS(至2016年5月，).

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).

:现已实施:全局

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

因此，您可以自己使用CMake脚本自己实现此目的-以@DevSolar的形式进行评论/答复，或类似于

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.

您可以利用这种情况，并通过将以下内容添加到全局CMakeLists.txt文件中来解决此问题:

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

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")
