Cmake项目效果很好。但是智能感知不起作用

Question

我正在Visual Studio 2017中学习cmake项目。它看起来不正常。但是构建和执行效果很好。为什么智能感知不起作用？

project directory(CMakeLists.txt, CMakeSettings.json)

main directory(main.c, CMakeLists.txt)
include directory(myprint.h)
printstatic directory(printstatic.c, CMakeLists.txt)
printshared directory(printshared.c, CMakeLists.txt)

“ myprint.h”

#include <stdio.h>

void print_test_static_library();
void print_test_shared_library();

“ main.c”

#include "myprint.h"

int main()
{
    for (int ii = 0; ii < 3; ++ii) {
        printf("Hello CMake..................\n");
        print_test_static_library();
        print_test_shared_library();
    }

    return 0;
}

“主要的CMakeLists.txt”

cmake_minimum_required (VERSION 3.8)

add_executable (main "main.c")
target_link_libraries(main printstatic printshared)

“ printstatic.c”

#include "myprint.h"

void print_test_static_library()
{
    printf("Test Static Library..................\n");
}

“ printstatic的CMakeLists.txt”

cmake_minimum_required (VERSION 3.8)

add_library (printstatic "printstatic.c")

“ printshared.c”

#include "myprint.h"

void print_test_shared_library()
{
    printf("Test Shared Library..................\n");
}

“ printshared的CMakeLists.txt”

cmake_minimum_required (VERSION 3.8)

add_library (printshared SHARED "printshared.c")

“项目的CMakeLists.txt”

cmake_minimum_required (VERSION 3.8)

set(CMAKE_C_STANDARD 99)

project ("CMakeProjectTest")

include_directories(${PROJECT_SOURCE_DIR}/include)
add_subdirectory ("printstatic")
add_subdirectory ("printshared")
add_subdirectory ("main")

“ CMakeSettings.json”

{
    "configurations": [
        {
            "name": "Linux-Debug",
            "generator": "Unix Makefiles",

在针对ARM时，这是Intellisense中的错误。 You are not the only one。

通过将项目目标切换到x64或x86，Intellisense应该正确地将代码解析为C99。如果需要以ARM为目标，则只需暂时忽略那些红线即可。

您可以通过两种方式向Microsoft提交错误报告。
