is not able to compile a simple test program.

It fails with the following output: Change Dir: /opt/tiger/code/DeepLM/build/CMakeFiles/CMakeTmp

Does it mean that the cuda toolkit is not installed properly? Can you nvcc other cuda code and run it correctly? If so, a simple solution would be "export PATH=$PATH:{Directory that contains your nvcc}", remove your cmake cache file and cmake configure again.
