如何配置CMake，以便生成的Visual Studio项目找到可执行文件?

本文介绍了如何配置CMake，以便生成的Visual Studio项目找到可执行文件?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我正在尝试在Windows上的Visual Studio 2017中使用CMake设置项目. CMakeLists.txt非常简单.我只是在添加带有源文件的可执行文件，然后将链接器语言指定为C ++.

I'm trying to set up a project with CMake in Visual Studio 2017 on Windows. The CMakeLists.txt is pretty simple. I am just adding an executable with source files and I specify the linker language to C++.

然后，我在build_64文件夹中运行cmake，并得到包含ALL_BUILD，ZERO_CHECK和我的实际项目的生成的VS解决方案.我将其设置为我的启动项目并尝试运行它，但随后出现此错误消息:

Then I run cmake in my build_64 folder and I get the generated VS solution containing ALL_BUILD, ZERO_CHECK and my actual project of course. I set it to be my start project and try to run it but then I get this error message:

无法启动程序'C:\ Users ... \ Documents \ MyProject \ build_64 \ Debug \ Project1.exe'.系统找不到指定的文件.

Unable to start program 'C:\Users...\Documents\MyProject\build_64\Debug\Project1.exe'.The system is unable to find the specified file.

CMakeLists.txt:

cmake_minimum_required(VERSION 3.2)
project(MyProject)

# create Project1
set(PROJECT1_SOURCES ${CMAKE_SOURCE_DIR}/Project1/src/)
add_executable(Project1 ${PROJECT1_SOURCES})
set_target_properties(Project1 PROPERTIES LINKER_LANGUAGE CXX)

cmake命令:

cmake .. -G "Visual Studio 15 2017 Win64"

为什么Visual Studio找不到我的可执行文件?以及如何配置它以便Visual Studio能够找到它?

Why can Visual Studio not find my executable? And how can I configure it so that Visual Studio finds it?

这是我的文件夹结构:

MyProject
   - build_64
       - ALL_BUILD.vcxproj
       ...
       - MyProject.sln
       - Project1.vcxproj
       - ZERO_CHECK.vcxproj
    - Project1
       - src
CMakeLists.txt
CMakeSettings.json

推荐答案

Cmake不会生成可执行文件-cmake为您创建了一个构建系统.然后，您需要在VS或命令行中构建项目.如果您需要处理一些可执行文件，然后再调用它，那么这里是您的摘录:

Cmake does not generate executable - cmake creates a build system for you. Then you need to build your project in VS or inside the command line.If you need to address some executable and later call it here is a snippet for you :

find_program(THRIFT_COMPILER NAMES thrift thrift.exe HINTS ${THRIFT_COMPILER_ROOT} ${THRIFT_ROOT}/compiler/cpp/bin ${THRIFT_ROOT}/bin ${THRIFT_ROOT}/bin/Release /usr/local /opt/local PATH_SUFFIXES bin bin64)

   exec_program(${THRIFT_COMPILER}
                  ARGS -version
                  OUTPUT_VARIABLE __thrift_OUT
                  RETURN_VALUE THRIFT_RETURN)
   message( STATUS "Thrift compiler version: ${__thrift_OUT}" )
