虽然我已经担任软件工程师十年了，但我对 cmake 和 Visual Studio 代码都是新手。我只是从来没有使用过这些工具。按照微软的文档，我将 vcpkg 设置为我的包管理器。
我已经像这样设置了我的 CMakeList.txt 。我有 2 个可执行文件。一个用于主项目，一个用于运行测试（RunTests.exe）
cmake_minimum_required(VERSION 3.10)
project(Geodesic-RayTracer)
set(CMAKE_CXX_STANDARD 14)
set(CMAKE_CXX_STANDARD_REQUIRED ON)
set(CMAKE_INCLUDE_CURRENT_DIR ON)
set(CMAKE_ARCHIVE_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/lib)
set(CMAKE_LIBRARY_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/lib)
set(CMAKE_RUNTIME_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/bin)
add_executable(Geodesic-RayTracer Source/Main.cpp)
# gtest stuff TODO make this a add_subdirectory with its own cmakelist
find_package(gtest CONFIG REQUIRED)
include(CTest)
include(GoogleTest)
add_executable(Runtests Source/Tests/Runtests.cpp)
target_link_libraries(Runtests PRIVATE GTest::gtest GTest::gtest_main GTest::gmock GTest::gmock_main)
set(gtest_force_shared_crt ON CACHE BOOL "" FORCE) # For Windows: Prevent overriding the parent project's compiler/linker settings
#TODO see if I can make this automatically pick up .cpp files
target_sources(Runtests PRIVATE Source/Tests/ExampleTest.cpp)
gtest_discover_tests(Runtests)
但是 CTest 似乎没有接受任何测试。在使用 CMake 插件的 Visual Studio Code 1.89.1 的“测试”窗口中，我看到了我的项目名称，但其下没有测试。当我单击运行时，我得到以下输出。我用星号编辑了一些个人信息

我想通了。首先我发现 VS Code 有一个 CMake 调试器。非常便利！事实证明，在我的 RunTests 主文件中，我忽略了将 argc 和 argv 传递到testing::InitGoogleTest。因此，当 gtest_discover_tests 尝试在 RunTests.exe 上使用 --gtest-list-tests 时，它正在运行测试而不是列出它们。这不是预期的输出，它只是默默地失败了
