CMake中的项目构建配置 [英] Project build configuration in CMake

问题描述

我的问题与 CMake：根据CMake生成的项目中的配置，更改Visual Studio和Xcode可执行文件的名称。在那篇文章中，输出文件名将根据项目配置（Debug，Release等）而改变。我想走得更远。当我知道项目的配置时，我想告诉可执行程序根据项目配置链接不同的库名称。我想知道CMake中是否有一个变量可以告诉项目配置。如果存在这样的变量，我的任务将变得更容易：

My question is very similar to CMake : Changing name of Visual Studio and Xcode exectuables depending on configuration in a project generated by CMake. In that post the output file name will change according to the project configuration (Debug, Release and so on). I want to go further. When I know the configuration of the project, I want to tell the executable program to link different library names depending on project configurations. I was wondering whether there is a variable in CMake that can tell the project configuration. If there exists such a variable, my task will become easier:

if (Project_Configure_Name STREQUAL "Debug")
   #do some thing
elseif (Project_Configure_Name STREQUAL "Release")
   #do some thing
endif()

推荐答案

根据 http://cmake.org/cmake/help/v2.8.8/cmake.html#command:target_link_libraries ，您可以根据配置指定库，例如：

According to http://cmake.org/cmake/help/v2.8.8/cmake.html#command:target_link_libraries, you can specify libraries according to the configurations, for example:

target_link_libraries(mytarget
  debug      mydebuglibrary
  optimized  myreleaselibrary
)

请注意，优化模式意味着所有非调试的配置。

Be careful that the optimized mode means every configuration that is not debug.

以下是一个更复杂但更可控制的解决方案：

Following is a more complicated but more controllable solution:

假设您要链接到导入的库（未在你的c制作项目），您可以使用以下方式添加它：

Assuming you are linking to an imported library (not compiled in your cmake project), you can add it using:

add_library(foo STATIC IMPORTED)
set_property(TARGET foo PROPERTY IMPORTED_LOCATION_RELEASE c:/path/to/foo.lib)
set_property(TARGET foo PROPERTY IMPORTED_LOCATION_DEBUG   c:/path/to/foo_d.lib)
add_executable(myexe src1.c src2.c)
target_link_libraries(myexe foo)
