C++ 如何为VS2019在忍者和叮当上添加包含路径？

因此，我想使用CMake和clang作为VS2019的前端，用额外的include路径构建我的项目

我已经尝试过的：

• CMakeLists.txt

• CMakeSettings.json

• test-llvm.cpp

#包括
int main（）
{
std：：cout我修改了CMakeList.txt如下，似乎已经解决了

# 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")

你试过了吗？试着添加
target\u include\u目录（test llvm PRIVATE“${CMAKE\u CURRENT\u SOURCE\u DIR}/include”）
。应该会有帮助的。谢谢你的有用评论。这似乎可以通过include\u directories命令解决。
