cmake - 如何将自定义构建类型添加到cmake？ (定位品牌)

Question

我正在尝试为我的cmake构建添加自定义构建类型，目标是代码覆盖率。

我已经找到有关它的FAQ条目:https://gitlab.kitware.com/cmake/community/wikis/FAQ#how-can-i-specify-my-own-configurations-for-generators-that-allow-it-

但是，我无法使其工作。

这是我的代码，使用cmake 2.8.5:

message("* Adding build types...")
if(CMAKE_CONFIGURATION_TYPES)
   list(APPEND CMAKE_CONFIGURATION_TYPES CodeCoverage)
   list(REMOVE_DUPLICATES CMAKE_CONFIGURATION_TYPES)
   set(CMAKE_CONFIGURATION_TYPES "${CMAKE_CONFIGURATION_TYPES}" CACHE STRING
       "Add the configurations that we need"
       FORCE)
   message("  Available build types are now : ${CMAKE_CONFIGURATION_TYPES}")
else()
   message("  XXX custom build types are not allowed...")
endif()

我得到“不允许使用XXX自定义构建类型...” ...

发现了问题:添加自定义构建和自定义配置之间存在混淆:

配置用于特殊工具，例如Visual Studio或XCode

构建类型是更加原始的功能

因此，要添加自定义构建类型，根本不需要操纵CMAKE_CONFIGURATION_TYPES变量。只需设置相应的变量并开始使用它，就像 explained一样:

SET(GCC_DEBUG_FLAGS "-g -Wall")

# Add new build types
message("* Adding build types...")
SET(CMAKE_CXX_FLAGS_COVERAGE
    "${GCC_DEBUG_FLAGS} -fprofile-arcs -ftest-coverage"
    CACHE STRING "Flags used by the C++ compiler during coverage builds."
    FORCE )
SET(CMAKE_C_FLAGS_COVERAGE
    "${GCC_DEBUG_FLAGS} -fprofile-arcs -ftest-coverage"
    CACHE STRING "Flags used by the C compiler during coverage builds."
    FORCE )
SET(CMAKE_EXE_LINKER_FLAGS_COVERAGE
    ""
    CACHE STRING "Flags used for linking binaries during coverage builds."
    FORCE )
SET(CMAKE_SHARED_LINKER_FLAGS_COVERAGE
    ""
    CACHE STRING "Flags used by the shared libraries linker during coverage builds."
    FORCE )
MARK_AS_ADVANCED(
    CMAKE_CXX_FLAGS_COVERAGE
    CMAKE_C_FLAGS_COVERAGE
    CMAKE_EXE_LINKER_FLAGS_COVERAGE
    CMAKE_SHARED_LINKER_FLAGS_COVERAGE )

我们可能还想审核帮助字符串(顺便说一句，以及 setting the default build type):

IF(NOT CMAKE_BUILD_TYPE)
   SET(CMAKE_BUILD_TYPE Debug
       CACHE STRING "Choose the type of build : None Debug Release RelWithDebInfo MinSizeRel Coverage."
       FORCE)
ENDIF(NOT CMAKE_BUILD_TYPE)
message("* Current build type is : ${CMAKE_BUILD_TYPE}")

关于尝试从执行此操作的另一个构建类型继承默认选项的警告:

SET(CMAKE_CXX_FLAGS_COVERAGE
    "${CMAKE_CXX_FLAGS_DEBUG} -fprofile-arcs -ftest-coverage"
    CACHE STRING "Flags used by the C++ compiler during coverage builds."
    FORCE )

这是 不好的想法，因为每次重新获得配置时(每次您对其进行更改时)，都会继续附加附加选项。
