CMake C++；编译命令 我目前正在学习CGUD，我理解它是一个构建文件生成器，我想看看CMake运行的命令，编译并链接我的C++文件。例如，如果我使用一个文件main.cpp，并且要用gcc编译它，我会运行gcc-o main.cpp。我如何看到CMake正在运行的C++命令？我尝试了使VBOSE = 1 但这只显示了CuScript相关命令而不是C++编译器命令。 // main.cpp #include <iostream> int main() { std::cout << "Hello world" << std::endl; } //CMakeLists.txt cmake_minimum_required(VERSION 3.2) project(example LANGUAGES CXX) add_executable(main main.cpp)

make VERBOSE=1

有没有一个选项可以让你得到这个。我不认为这是CMake的责任。@john我编辑以使其更清楚，是的，我尝试了

make

和

make VERBOSE=1

，但它只显示与CMake相关的命令。如果我查看MaFe文件，它只包含CGuess相关命令和C++编译器相关命令。有点Google显示，使VBOSE＝1 是正确答案。makefile只能包含make命令，它包含CMake命令是没有意义的（否则您将需要CMake而不是make来运行它）。我想我们必须看看您生成的makefile的示例。请尽可能简单。我刚刚添加了一个hello world示例，其中包含所有相关文件以及使用

make VERBOSE=1

返回的消息。正如在最后一个代码块中可以看到的，没有提到C++文件是如何被编译的，这就是我想知道的。但是在你的输出中，
