Resolve CUDA compile check error in CMAKE

In one word: change #if _MSC_VER < 1600 || _MSC_VER > 1900 to #if _MSC_VER < 1600 || _MSC_VER > 1999 in host_config.h

Using CMake to help compile tensorflow with GPU ops, we first check CUDA compatibility:

try_compile(CUDA_TEST_COMPILE_C
    ${CMAKE_CURRENT_BINARY_DIR}/tests/cuda
    ${CMAKE_CURRENT_SOURCE_DIR}/tests/cuda/compatibility_test.c
    CMAKE_FLAGS -DINCLUDE_DIRECTORIES=${CUDA_INCLUDE_DIRS})
try_compile(CUDA_TEST_COMPILE_CXX
    ${CMAKE_CURRENT_BINARY_DIR}/tests/cuda
    ${CMAKE_CURRENT_SOURCE_DIR}/tests/cuda/compatibility_test.cc
    CMAKE_FLAGS -DINCLUDE_DIRECTORIES=${CUDA_INCLUDE_DIRS})

In your CUDA installation headers, with a file include/crt/host_config.h, there is a block

#if defined(_WIN32)

#if _MSC_VER < 1600 || _MSC_VER > 1900

#error -- unsupported Microsoft Visual Studio version! Only the versions 2012, 2013, 2015 and 2017 are supported!

#elif _MSC_VER == 1600 /* _MSC_VERION == 1600 */

#pragma message("support for Microsoft Visual Studio 2010 has been deprecated!")

#endif /* _MSC_VER < 1600 || _MSC_VER > 1800 || _MSC_VERSION == 1600 */

#endif /* _WIN32 */

Here they check _MSC_VER and make sure not less than 1600 or greater than 1900. The problem is _MSC_VER > 1900 here! In fact the current _MSC_VER in VS2017 15.8.1 is 1915, while no error was found in my compilation with the version newer than 1900. So you just feel free to change this number to anything greater than 1915!
