[QST] Errors about using CUTLASS within other applications

[MoCHEN-WHU]

Hello, I am new to using cutlass and I am trying to use it within other applications as Using CUTLASS within other applications. I have created a directory called my_test which contains my_test.cpp (the "print" example code) and CMakeLists.txt.

project(MY_TEST)

set(CMAKE_CXX_STANDARD 17)

add_executable(my_test my_test.cpp)

include_directories(
    /root/cutlass/include
    /root/cutlass/tools/util/include
    )

However, the compiler is unable to locate the CUDA include directory.

[ 50%] Building CXX object CMakeFiles/my_test.dir/my_test.cpp.o
In file included from /root/cutlass/include/cutlass/numeric_types.h:77,
                 from /root/cutlass/my_test/my_test.cpp:3:

   73 | #include <cuda_fp16.h>
      |          ^~~~~~~~~~~~~
compilation terminated.

I try to add it explicitly as

include_directories(
    /usr/local/cuda/include
    /root/cutlass/include
    /root/cutlass/tools/util/include
    )

Then the errors happen in platform.h
