彻底解决低版本boost在新版CUDA下编译出错的问题
解决marian在Ubuntu上的编译问题：
在安装了boost 1.58 - 1.65左右的版本时，编译会报错：
In file included from /usr/local/cuda-10.2/include/cuda_runtime.h:115:0,
from :0:
/usr/local/cuda-10.2/include/crt/common_functions.h:74:24: error: token ""__CUDACC_VER__ is no longer supported. Use __CUDACC_VER_MAJOR__, __CUDACC_VER_MINOR__, and __CUDACC_VER_BUILD__ instead."" is not valid in preprocessor expressions
#define __CUDACC_VER__ "__CUDACC_VER__ is no longer supported. Use __CUDACC_VER_MAJOR__, __CUDACC_VER_MINOR__, and __CUDACC_VER_BUILD__ instead."
^
这个问题坑在没有给出引用/usr/local/cuda-10.2/include/cuda_runtime.h的文件，止步于：

第一步：
使用make VERBOSE=1 重新编译，得到下面信息：
/usr/local/cuda-10.2/bin/nvcc -M -D__CUDACC__ marian/src/tensors/gpu/tensor_operators.cu -o marian/build/src/CMakeFiles/marian_cuda.dir/tensors/gpu/marian_cuda_generated_tensor_operators.cu.o.NVCC-depend -m64 -DBLAS_FOUND=1 -DMKL_FOUND=1 -DCUDA_FOUND -DUSE_NCCL --default-stream per-thread -O3 -g --use_fast_math -gencode=arch=compute_60,code=sm_60 -gencode=arch=compute_61,code=sm_61 -gencode=arch=compute_70,code=sm_70 -gencode=arch=compute_70,code=compute_70 -ccbin /usr/bin/cc -std=c++11 -Xcompiler -fPIC -Xcompiler -Wno-unused-result -Xcompiler -Wno-deprecated -Xcompiler -Wno-pragmas -Xcompiler -Wno-unused-value -Xcompiler -Werror -Xcompiler -msse2 -Xcompiler -msse3 -Xcompiler -msse4.1 -Xcompiler -msse4.2 -Xcompiler -mavx -Xcompiler -mavx2 -DNVCC -I/usr/local/cuda-10.2/include -I/opt/intel/compilers_and_libraries_2019.1.144/linux/mkl/include -Imarian/src -Imarian/src/. -Imarian/src/3rd_party -Imarian/src/3rd_party/SQLiteCpp/include -Imarian/src/3rd_party/sentencepiece -Imarian/src/3rd_party/fbgemm/include -Imarian/build/local/include

第二步：
在nvcc后加上 -v 选项，重新执行上面的nvcc编译指令，得到下面输出：
"/usr/bin"/cc -std=c++11 -D__CUDA_ARCH__=600 -E -x c++ -DCUDA_DOUBLE_MATH_FUNCTIONS -D__CUDACC__ -D__NVCC__ -fPIC -Wno-unused-result -Wno-deprecated -Wno-pragmas -Wno-unused-value -Werror -msse2 -msse3 -msse4.1 -msse4.2 -mavx -mavx2 -O3 -I"/usr/local/cuda-10.2/include" -I"/opt/intel/compilers_and_libraries_2019.1.144/linux/mkl/include" -I"marian/src" -I"marian/src/." -I"marian/src/3rd_party" -I"marian/src/3rd_party/SQLiteCpp/include" -I"marian/src/3rd_party/sentencepiece" -I"marian/src/3rd_party/fbgemm/include" -I"marian/build/local/include" "-I/usr/local/cuda-10.2/bin/../targets/x86_64-linux/include" -D "__CUDACC__" -D "BLAS_FOUND=1" -D "MKL_FOUND=1" -D "CUDA_FOUND" -D "USE_NCCL" -D "NVCC" -D__CUDACC_VER_MAJOR__=10 -D__CUDACC_VER_MINOR__=2 -D__CUDACC_VER_BUILD__=89 -DCUDA_API_PER_THREAD_DEFAULT_STREAM=1 -include "cuda_runtime.h" -m64 -g -gdwarf-2 "marian/src/tensors/gpu/tensor_operators.cu" -o "/tmp/tmpxft_00004b67_00000000-7_tensor_operators.compute_60.cpp1.ii"
第三步：
继续在cc后加上 -v选项，重新执行上面的cc编译指令，得到下面输出：

第四步：
由于cc1plus已经加上了-v参数，最后的输出也并未比最开始多出有用信息，故只能使用strace来打印出所有系统调用。在上面命令前加上strace，并重新执行，得到下面信息：

可以看到在出错前，open的最后一个文件是/usr/local/include/boost/config/compiler/nvcc.hpp，因此可以推断问题和boost。
继续向上回溯，可以找到出错前最后打开的最后一个工程内的文件是marian/src/3rd_party/CLI/Optional.hpp
这个文件中使用了__has_include这个C++11新提供的宏，根据文件是否存在来决定是否include，来实现选择性include。
可能是这个新特性导致编译器无法输出引用/usr/local/cuda-10.2/include/cuda_runtime.h的文件。
解决方案：
由于定位到boost，很容易就能发现是/usr/local/include/boost/config/compiler/nvcc.hpp中使用了__CUDACC_VER__。
这个问题有两中方式解决：
一是升级boost库版本，升级到1.65以上。
二是在CMakeList.txt中CUDA_NVCC_FLAGS中加上-DCLI11_BOOST_OPTIONAL=0，禁止使用boost option
