maybe some advices for cmake about fastertransformer

[zhanzy178]

and it seems some cmake files lack -lmpi_cxx, so there are some compile errors

Thanks for your advise! I met this error and fixed it by adding -lmpi_cxx -lmpi to target_link_libraries in CMakeLists.txt and sample/cpp/CMakeLists.txt

We will solve the issue 2 and 3 first.
And for issue 1, we will take some time to check.
Do you encounter any problem due to lacking -lmpi_cxx?

yes, I encountered a "undefined reference to ompi_mpi_cxx_op_intercept "etc. , just like: https://stackoverflow.com/questions/17548436/openmpi-error-during-compilation.
with -DBUILD_GPT=ON -DBUILD_TF=ON，and set the LD_LIBRARY_PATH, sample/cpp/gpt_sample.cc throws that error

Do you run on different environment? You can propose a pull request to fix the bug since we can reproduce it in the docker we recommend.

Yes, I run on a different environment, my mpi is openmpi 1.8.5. Alright, I get it~
