Description:
When compiling c++ code that references tensorflow_cc.so library, following linking errors occur:
/usr/bin/ld: /usr/lib/libtensorflow_cc.so: undefined reference to `omp_in_parallel@VERSION'
/usr/bin/ld: /usr/lib/libtensorflow_cc.so: undefined reference to `GOMP_barrier@VERSION'
/usr/bin/ld: /usr/lib/libtensorflow_cc.so: undefined reference to `omp_get_max_threads@VERSION'
/usr/bin/ld: /usr/lib/libtensorflow_framework.so: undefined reference to `kmp_set_blocktime@VERSION'
/usr/bin/ld: /usr/lib/libtensorflow_cc.so: undefined reference to `omp_get_num_threads@VERSION'
/usr/bin/ld: /usr/lib/libtensorflow_cc.so: undefined reference to `omp_get_thread_num@VERSION'
/usr/bin/ld: /usr/lib/libtensorflow_cc.so: undefined reference to `GOMP_parallel@VERSION'
/usr/bin/ld: /usr/lib/libtensorflow_framework.so: undefined reference to `omp_set_num_threads@VERSION'
collect2: error: ld returned 1 exit status
make[2]: *** [CMakeFiles/my_project.dir/build.make:99: my_project] Error 1
make[1]: *** [CMakeFiles/Makefile2:83: CMakeFiles/my_project.dir/all] Error 2
make: *** [Makefile:91: all] Error 2

These errors are new and did not occur in the previous version of the package I had installed

I wrote a script to search for libraries referencing one of these symbols:
File: /usr/lib/libcaffe2_detectron_ops_gpu.so
109: 0000000000000000 0 FUNC GLOBAL DEFAULT UND omp_in_parallel@OMP_1.0 (22)

213: 0000000000000000 0 FUNC GLOBAL DEFAULT UND omp_in_parallel@OMP_1.0 (29)
---------
and it looks like in tensorflow libraries, library version is invalid for some reason (@VERSION where @OMP_1.0 would probably work)
This doesn't interfere with python code loading tensorflow libraries, but c++ code becomes inoperable

Steps to reproduce:
main.cpp:
#include <tensorflow/cc/client/client_session.h>
#include <tensorflow/cc/ops/standard_ops.h>
#include <tensorflow/core/framework/tensor.h>
#include <tensorflow/core/public/session.h>

using namespace tensorflow;
using namespace tensorflow::ops;

int main() {
// tensorflow::data::DataseT::
using namespace tensorflow;
using namespace tensorflow::ops;

// Create a root scope.
Scope root = Scope::NewRootScope();

// Create a constant tensor of shape {2, 2}.
auto a = Const(root, {{1.f, 2.f}, {3.f, 4.f}});

// Create a graph.
GraphDef graph_def;
TF_CHECK_OK(root.ToGraphDef(&graph_def));

// Create a session and associate the graph with it.
SessionOptions session_options;
std::unique_ptr<Session> session(NewSession(session_options));
TF_CHECK_OK(session->Create(graph_def));

std::vector<Tensor> outputs;

// Evaluate the tensor `a`.
TF_CHECK_OK(
session->Run({/* No inputs */}, {a.node()->name()}, {}, &outputs));

// Print the result.
LOG(INFO) << outputs[0].matrix<float>();

// Close the session.

auto status = session->Close();
if (!status.ok()) {
std::cerr << "Error closing session: " << status.ToString()
<< std::endl;
}

return 0;
}
