chore: ensure ctest can detect gtest unit tests

[BLumia]

此提交使 CMake 可以通过 gtest 提供的支持发现单元测试，旨在让 IDE 等工具可以更方便的识别并运行单个单元测试而不是每次都跑完整的一组测试。

Summary by Sourcery

Enhancements:

• Include the GoogleTest CMake module and invoke gtest_discover_tests in CMakeLists for taskmanager panel tests to auto-register each test case with CTest.

我来对这个CMakeLists.txt的变更进行审查：

1. 语法逻辑审查：

• 语法正确，没有明显的语法错误
• 使用了标准的CMake命令和变量
• 变更内容是合法的CMake语法

2. 代码质量改进：

• 将add_test改为gtest_discover_tests是一个很好的改进
• gtest_discover_tests可以自动发现测试用例，比手动指定更灵活
• 添加了include(GoogleTest)是必要的，因为使用了gtest_discover_tests

3. 性能考虑：

• 这个变更不会影响运行时性能
• 在构建时可能会有轻微的开销，因为gtest_discover_tests需要扫描测试文件
• 但这个开销是值得的，因为它提供了更好的测试管理

4. 安全性考虑：

• 没有直接的安全影响
• 使用gtest_discover_tests可能会更安全，因为它可以确保所有测试都被发现和运行

5. 建议和改进：

• 变更本身是好的，但建议在文件开头添加注释说明为什么使用gtest_discover_tests
• 可以考虑添加版本检查，确保GoogleTest模块的版本兼容性
• 建议保持一致的代码风格，比如删除了最后的空行，建议保留

6. 其他建议：

# 添加版本检查
if(CMAKE_VERSION VERSION_LESS "3.10")
    message(FATAL_ERROR "CMake 3.10 or higher is required for gtest_discover_tests")
endif()

# 添加注释说明
# Use gtest_discover_tests for automatic test discovery instead of manually specifying tests
include(GoogleTest)

总的来说，这个变更是积极的，它提高了测试的可维护性和自动化程度。建议可以采纳，但最好添加一些注释和版本检查来提高代码的可读性和健壮性。
