Hi，
when I run

cmake .. \
   -DCMAKE_BUILD_TYPE=Release \
   -DCMAKE_PREFIX_PATH=$TANDEM_LIBTORCH_DIR \
   -DCUDNN_LIBRARY=$TANDEM_CUDNN_LIBRARY \
   -DCUDNN_INCLUDE_PATH=$TANDEM_CUDNN_INCLUDE_PATH

there are some errors:

how to fix it ? Thanks!

Have you ever modified the cmake file? Try to git clone again.
