从CMakeLists.txt设置诊断：插入符号 [英] set diagnostics:caret from CMakeLists.txt

问题描述

我想使用Visual Studio 2017中的新的（更好的）诊断信息。

I would like to use the new (and better) diagnostic information from visual studio 2017.

要立即声明我所有项目的功能我的CMakeLists.txt中的此标志

To have it enabled to all my project at once I want to declare this flag from my CMakeLists.txt

我尝试

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} /diagnostics:caret")

但是编译时出现错误，即/ diagnostics：classic（默认值）与/ diagnostics：caret

But when compiling there is an error saying that /diagnostics:classic (which is the default value) is not compatible with /diagnostics:caret

是否可以使用cmake覆盖默认值？

Is there a way to override the default value using cmake ?

推荐答案

您只需要知道CMake尚未正式支持的VS编译器选项将最终出现在以下位置：

You just have to know that VS compiler options that CMake does not yet officially support will end up under:

属性 / C / C ++ / 命令行 / 其他选项

Properties/C/C++/Command Line/Additional Options

这就是为什么你得到

cl : Command line error D8016: '/diagnostics:classic' and '/diagnostics:caret' 
                               command-line options are incompatible

但是您可以给 cl 选项在全球范围内使用新的 VS_USER_PROPS 目标属性（版本> = 3.8）。

But you can give cl options globally with the new VS_USER_PROPS target property (version >= 3.8).

这是一个有效的示例：

CMakeLists.txt

cmake_minimum_required(VERSION 3.0)

project(VSAnyFlag)

file(WRITE main.cpp "int main() { return 0; }")
add_executable(${PROJECT_NAME} main.cpp)

file(WRITE "${CMAKE_CURRENT_BINARY_DIR}/${PROJECT_NAME}.Cpp.user.props" [=[
<?xml version="1.0" encoding="utf-8"?> 
<Project DefaultTargets="Build" ToolsVersion="15.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
    <ItemDefinitionGroup>
        <ClCompile>
            <DiagnosticsFormat>Caret</DiagnosticsFormat>
        </ClCompile>
    </ItemDefinitionGroup>
</Project>
]=])

set_target_properties(
    ${PROJECT_NAME}
    PROPERTIES
        VS_USER_PROPS "${PROJECT_NAME}.Cpp.user.props"
)    

参考

• 使用CMake添加Visual C ++属性表

• Add Visual C++ property sheets using CMake
