我正在尝试为CMake测试设置工作目录,但似乎无法使其工作。以下是我正在尝试使用的非常简单的测试:
CMakeLists.txt
cmake_minimum_required(VERSION 3.24)
set (CMAKE_CXX_STANDARD 17)
project(working_directory_error LANGUAGES CXX)
enable_testing()
add_executable(main main.cpp)
add_test(main_test main WORKING_DIRECTORY "C:/")
main.cpp
#include <filesystem>
#include <iostream>
int main()
{
std::filesystem::path workingDirectory = std::filesystem::current_path();
bool workingDirectoryIsC = workingDirectory == std::filesystem::path("C:/");
std::cout << "Working directory is " << workingDirectory << " which is "
<< (workingDirectoryIsC ? "right" : "wrong") << std::endl;
return workingDirectoryIsC ? 0 : 1;
}
安慰

我在Windows上尝试过MSVC和Ninja生成器,在Linux上也尝试过使用WSL的Ninja生成器。我试着从
out
文件夹在案例中
--test-dir
以某种方式覆盖了工作目录。似乎什么都不起作用。
有什么明显的东西我遗漏了吗?
