文件夹目录是

CMAKE-GOOD
-build
-CMakeLists.txt
-main.cpp

这是cmakelists.txt

cmake_minimum_required(VERSION 3.14)

project(MyProject VERSION 1.0.0)

add_executable(cmake-good main.cpp)

这是main.cpp

#include <iostream>
int main()
{
    std::cout << "hello, world! \n";
}

当我在~desktop/cmake_tutorial_cmake_good/build中键入cmake--build.时，它显示一个错误

(base) bmssa@bmssa:~/Desktop/CMake_tutorial/CMAKE-GOOD/build$ cmake --build .

就像我听到的CMake-build。与make相似，所以我尝试了make，它显示了如下错误

(base) bmssa@bmssa:~/Desktop/CMake_tutorial/CMAKE-GOOD/build$ make

当我键入cmake-version时,

cmake version 3.20.0

CMake suite maintained and supported by Kitware (kitware.com/cmake).

你能帮我修好它吗？我不能做任何事情，因为我甚至不能解决这个简单的错误在非常容易的教程。请帮帮我请谢谢

ps.因为我都不知道什么是CMake中的错误，你能告诉我应该在google中键入什么来解决这个问题吗？

Taget的食谱？目标“all”的制作方法失败？

不知道在谷歌里该打什么....
