【问题描述】：
我正在尝试使用here 描述的方法创建自定义cmake_configuration_type
我面临的问题是第 3 方库的正确链接。例如，当我创建自定义配置时，可执行文件未正确链接到最终配置的第三方库。链接到的一些库处于发布模式，而其他库处于调试模式。有人会指出我 CMake 是否提供了解决此问题的方法吗？
这是所要求的代码： CMakeLists.txt：
cmake_minimum_required(VERSION 3.5)
project(DisplayImage)
list(APPEND CMAKE_MODULE_PATH ${CMAKE_SOURCE_DIR}/CMake)
# Add configurations
include(SetupConfiguration)
# if (WIN32)
# # Restrict the generated configuration to be what we configured above.
# # No point creating project files for build types that will not compile.
# # Note: it's set to FORCE so that both CMAKE_BUILD_TYPE and CMAKE_CONFIGURATION_TYPES match up.
# set(CMAKE_CONFIGURATION_TYPES ${CMAKE_BUILD_TYPE} CACHE STRING "Build configurations to generate." FORCE)
# mark_as_advanced(CMAKE_CONFIGURATION_TYPES)
# endif()
message("Generated with config types: ${CMAKE_CONFIGURATION_TYPES}")
######################################################################
# Choose C++ standard. Currently 11, as we try to support VS2013.
######################################################################
set(mp_CXX_STANDARD 11)
set(CMAKE_CXX_EXTENSIONS 0)
set(CMAKE_CXX_STANDARD ${mp_CXX_STANDARD})
set(CMAKE_CXX_STANDARD_REQUIRED ON)
######################################################################
# Add Optional Requirements
######################################################################
if(WIN32)
set(_library_sub_dir "bin")
else()
set(_library_sub_dir "lib")
endif()
find_package( OpenCV REQUIRED )
add_executable(DisplayImage main.cpp)
target_link_libraries(DisplayImage ${OpenCV_LIBS})
if (CMAKE_CONFIGURATION_TYPES MATCHES Release)
set_property(TARGET DisplayImage PROPERTY MSVC_RUNTIME_LIBRARY "MultiThreaded$<$<CONFIG:Release>:Release>")
set_target_properties(DisplayImage PROPERTIES RELEASE_POSTFIX "R")
elseif(CMAKE_CONFIGURATION_TYPES MATCHES Final)
set_property(TARGET DisplayImage PROPERTY MSVC_RUNTIME_LIBRARY "MultiThreaded$<$<CONFIG:Release>:Release>")
set_target_properties(DisplayImage PROPERTIES RELEASE_POSTFIX "F")
target_compile_definitions(DisplayImage PUBLIC -DFINAL)
elseif(CMAKE_CONFIGURATION_TYPES MATCHES Debug)
set_property(TARGET DisplayImage PROPERTY MSVC_RUNTIME_LIBRARY "MultiThreaded$<$<CONFIG:Debug>:Debug")
set_target_properties(DisplayImage PROPERTIES DEBUG_POSTFIX "D")
endif()
main.cpp
#include <stdio.h>
#include <opencv2/opencv.hpp>
using namespace cv;
int main(int argc, char** argv )
{
if ( argc != 2 )
{
printf("usage: DisplayImage.out <Image_Path>\n");
return -1;
}
Mat image;
image = imread( argv[1], 1 );
if ( !image.data )
{
printf("No image data \n");
return -1;
}
namedWindow("Display Image", WINDOW_AUTOSIZE );
imshow("Display Image", image);
waitKey(0);
return 0;
}
在项目的CMake文件夹下有以下两个文件mpSetupMSVCRuntime.cmake
if(MSVC)
set(variables
CMAKE_C_FLAGS_DEBUG
CMAKE_C_FLAGS_MINSIZEREL
CMAKE_C_FLAGS_RELEASE
CMAKE_CXX_FLAGS_DEBUG
CMAKE_CXX_FLAGS_RELEASE
CMAKE_CXX_FLAGS_RELWITHDEBINFO
)
add_definitions(/bigobj)
add_definitions(/MP)
endif()
和 SetupConfiguration.cmake
if(NOT SET_UP_CONFIGURATIONS_DONE)
set(SET_UP_CONFIGURATIONS_DONE TRUE)
get_property(isMultiConfig GLOBAL PROPERTY GENERATOR_IS_MULTI_CONFIG)
if(isMultiConfig)
set(CMAKE_CONFIGURATION_TYPES "Debug;Release;Final" CACHE STRING "" FORCE)
else()
if(NOT CMAKE_BUILD_TYPE)
message("Defaulting to release build.")
set(CMAKE_BUILD_TYPE Release CACHE STRING "" FORCE)
endif()
set_property(CACHE CMAKE_BUILD_TYPE PROPERTY HELPTSTRING "Choose the type of build")
#set the valid options for cmake-gui drop-down list
set_property(CACHE CMAKE_BUILD_TYPE PROPERTY STRINGS "Debug;Release;Final")
endif()
# now set up the Final configuration
set(CMAKE_C_FLAGS_FINAL "${CMAKE_C_FLAGS_RELEASE}" CACHE STRING "" FORCE)
set(CMAKE_CXX_FLAGS_FINAL "${CMAKE_CXX_FLAGS_RELEASE}" CACHE STRING "" FORCE)
set(CMAKE_EXE_LINKER_FLAGS_FINAL "${CMAKE_EXE_LINKER_FLAGS_RELEASE}" CACHE STRING "" FORCE)
set(CMAKE_SHARED_LINKER_FLAGS_FINAL "${CMAKE_SHARED_LINKER_FLAGS_RELEASE}" CACHE STRING "" FORCE)
set(CMAKE_MODULE_LINKER_FLAGS_FINAL "${CMAKE_MODULE_LINKER_FLAGS_RELEASE}" CACHE STRING "" FORCE)
endif()
感谢您的帮助
【问题讨论】：
-
您能否提供一个示例 CMake 文件，显示如何链接您的第三方库？一般来说，这就是 CMake generator expressions 的用途。
-
如果没有您使用的库的示例，很难说出了什么问题。
-
我还要补充一点，这只是一个例子，在实际项目中有几个第三方库。
