如何使用CMake使C / C ++混合项目工作

Question

我有一个混合的C / C ++项目，可以成功地使用Makefile进行编译和运行（如果需要，请这样说）。 我想使用CMake构建项目。我的CMakeLists.txt看起来如下

cmake_minimum_required(VERSION 3.13)
project(project_name)

set(CMAKE_CXX_STANDARD 11)

include_directories(include)

add_executable(main
        src/some_file.cpp
        src/other_file.c
        ... and so on
)

我基本上有一个include /和src /文件夹，分别存放C和CPP源文件和头文件。

现在，在一个文件（utils.hpp）中，我加入了string和vector这样的向量。

#include <string>
#include <vector>

尝试构建时，我得到fatal error: 'string' file not found。 相反，我可以#include <string.h>来使错误消失，但是我得到fatal error: 'vector' file not found。非常奇怪的行为。我试图用非常简单的代码

设置一个简单的虚拟项目。

#include <iostream>
#include <string>
#include <vector>

int main() {
    std::vector<int> vec(3);
    std::cout << std::string("Hello, World!") << std::endl;
    return 0;
}

和最简单的CMakeLists.txt都为此文件添加了一个目标，与上面相同，并且一切正常。那么C / C ++的混合是否存在问题？是什么原因导致这些问题？

编译器信息：

这是我的CMakeLists.txt

cmake_minimum_required(VERSION 3.13)
project(fastcode)

set(CMAKE_CXX_STANDARD 11)

include_directories(include)

add_executable(benchmark
        src/benchmark.cpp
        src/hgwosca.c
        src/objectives.c
        src/penguin.c
        src/run_benchmark.cpp
        src/utils.cpp)

对于我项目中的以下文件。
