32410f80 - [Caffe2 CPU tests] Update CMakeLists.txt (#119643)

[Caffe2 CPU tests] Update CMakeLists.txt (#119643) I was trying to build PyTorch with USE_GLOG=ON (so we could get better timestamps around the nccl logging) and ran into this error ``` [1/7] Linking CXX executable bin/verify_api_visibility FAILED: bin/verify_api_visibility : && /opt/rh/gcc-toolset-11/root/usr/bin/c++ -D_GLIBCXX_USE_CXX11_ABI=1 -Wno-deprecated -fvisibility-inlines-hidden -DUSE_PTHREADPOOL -DUSE_KINETO -DLIBKINETO_NOROCTRACER -DUSE_FBGEMM -DUSE_QNNPACK -DUSE_PYTORCH_QNNPACK -DUSE_XNNPACK -DSYMBOLICATE_MOBILE_DEBUG_HANDLE -O2 -fPIC -Wall -Wextra -Werror=return-type -Werror=non-virtual-dtor -Werror=range-loop-construct -Werror=bool-operation -Wnarrowing -Wno-missing-field-initializers -Wno-type-limits -Wno-array-bounds -Wno-unknown-pragmas -Wno-unused-parameter -Wno-unused-function -Wno-unused-result -Wno-strict-overflow -Wno-strict-aliasing -Wno-stringop-overflow -Wsuggest-override -Wno-psabi -Wno-error=pedantic -Wno-error=old-style-cast -Wno-missing-braces -fdiagnostics-color=always -faligned-new -Wno-unused-but-set-variable -Wno-maybe-uninitialized -fno-math-errno -fno-trapping-math -Werror=format -Wno-stringop-overflow -DHAVE_AVX512_CPU_DEFINITION -DHAVE_AVX2_CPU_DEFINITION -O2 -g -DNDEBUG -rdynamic -Wl,--no-as-needed caffe2/CMakeFiles/verify_api_visibility.dir/__/aten/src/ATen/test/verify_api_visibility.cpp.o -o bin/verify_api_visibility -L/lib/intel64 -L/lib/intel64_win -L/lib/win-x64 -Wl,-rpath,/lib/intel64:/lib/intel64_win:/lib/win-x64:/usr/local/cuda/lib64:/root/conda/lib:/mnt/code/pytorch/build/lib: lib/libgtest_main.a -Wl,--no-as-needed,"/mnt/code/pytorch/build/lib/libtorch.so" -Wl,--as-needed -Wl,--no-as-needed,"/mnt/code/pytorch/build/lib/libtorch_cpu.so" -Wl,--as-needed lib/libprotobuf.a /root/conda/lib/libmkl_intel_lp64.so /root/conda/lib/libmkl_gnu_thread.so /root/conda/lib/libmkl_core.so -fopenmp /usr/lib64/libpthread.so -lm /usr/lib64/libdl.so -Wl,--no-as-needed,"/mnt/code/pytorch/build/lib/libtorch_cuda.so" -Wl,--as-needed lib/libc10_cuda.so lib/libc10.so /root/conda/lib/libglog.so.0.4.0 /root/conda/lib/libgflags.so.2.2.2 -lpthread /usr/local/cuda/lib64/libcudart.so /usr/local/cuda/lib64/libnvToolsExt.so lib/libgtest.a -pthread && /root/conda/bin/cmake -E __run_co_compile --lwyu="ldd;-u;-r" --source=bin/verify_api_visibility && : /opt/rh/gcc-toolset-11/root/usr/bin/ld: /mnt/code/pytorch/build/lib/libtorch.so: undefined reference to symbol '_ZTVN10__cxxabiv117__class_type_infoE@@CXXABI_1.3' /opt/rh/gcc-toolset-11/root/usr/bin/ld: /usr/lib64/libstdc++.so.6: error adding symbols: DSO missing from command line collect2: error: ld returned 1 exit status ``` Adding stdc++ explicitly to the list of libraries to link seems to fix the build, and I was able to get a working build of PyTorch.
