因此,我想使用CMake和clang作为VS2019的前端,使用其他包含路径构建我的项目。
我已经尝试过的方法:
# CMakeList.txt : CMake project for test-llvm, include source and define
# project specific logic here.
#
cmake_minimum_required (VERSION 3.8)
# Add source to this project's executable.
add_executable (test-llvm "test-llvm.cpp" "test-llvm.h")
# TODO: Add tests and install targets if needed.
set(INCLUDE_DIR "${CMAKE_CURRENT_SOURCE_DIR}/include")
{
"configurations": [
{
"name": "x64-Clang-Debug",
"generator": "Ninja",
"configurationType": "Debug",
"buildRoot": "${projectDir}\\out\\build\\${name}",
"installRoot": "${projectDir}\\out\\install\\${name}",
"cmakeCommandArgs": "",
"buildCommandArgs": "-v",
"ctestCommandArgs": "",
"inheritEnvironments": [ "clang_cl_x64" ],
"variables": []
},
{
"name": "x86-Clang-Release",
"generator": "Ninja",
"configurationType": "RelWithDebInfo",
"buildRoot": "${projectDir}\\out\\build\\${name}",
"installRoot": "${projectDir}\\out\\install\\${name}",
"cmakeCommandArgs": "",
"buildCommandArgs": "-v",
"ctestCommandArgs": "",
"inheritEnvironments": [ "clang_cl_x86" ],
"variables": []
}
]
}
#include <needtoinclude.h>
int main()
{
std::cout << "Hello world" << std::endl;
}
#pragma once
#include <iostream>
我得到哪些错误:

我应该如何添加包含路径?
答案 0 :(得分:0)
我如下修改了CMakeList.txt。看来已经解决了。
# CMakeList.txt : CMake project for test-llvm, include source and define
# project specific logic here.
#
cmake_minimum_required (VERSION 3.8)
# Add source to this project's executable.
add_executable (test-llvm "test-llvm.cpp" "test-llvm.h")
# TODO: Add tests and install targets if needed.
include_directories("include")
