Iyán,

Our FindTensorFlow.cmake file is used during the build to locate the TensorFlow
native libraries. It checks in /usr/lib, /usr/local/lib, and
/usr/local/lib/tensorflow_cc. If the libraries are not present at any of those
locations, a hint can be given using the TENSORFLOW_PATH variable.

This will hopefully work for you:

    cmake -DTENSORFLOW_PATH=<path to your tensorflow>

Also, the tensorflow_cc [1] project (which installs to a location
FindTensorFlow.cmake searches) has worked well for us in the past and may save
compilation time since it only builds the needed libraries.

Regards,

Andy I.C.
