如何解决GTest和LibTorch联动冲突

这个问题遵循了我的先例。

我正在用OpenCV，Torch和NumCpp编写一个C++程序。该程序现在可以编译和工作正常，但我需要编写单元测试。

我按照谷歌的教程在我的项目中构建GTest和GMock，但它失败了。当我不链接火炬库时，这行得通。

链接 GTest + 手电筒时出错：

/usr/bin/ld: CMakeFiles/TryGTest_test.dir/test/boxTest.cpp.o: in function `testing::AssertionResult testing::internal::CmpHelperEQFailure<int, int>(char const*, char const*, int const&, int const&)':
/tmp/tmp.Z1zXnMtLsD/cmake-build-debug-ubuntu_2/googletest-src/googletest/include/gtest/gtest.h:1511: undefined reference to `testing::internal::EqFailure(char const*, char const*, std::string const&, std::string const&, bool)'
collect2: error: ld returned 1 exit status

我想它来自 Libtorch 定义与 Gtest 同名的宏，谷歌提出了一种解决方法来解决此类问题，但我需要找到哪个宏失败了。

希望有人能帮忙！
