Failed to compute shorthash for libnvrtc.so

Question

следовал согласно инструкции по установки c++ pytorch https://pytorch.org/cppdocs/installing.html скачал cuda toolkit с официального сайта 12.1 , скачал пакет libtorch с cuda 12. 1 cmake :

cmake_minimum_required(VERSION 3.18 FATAL_ERROR)
project(example-app)

find_package(Torch REQUIRED)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} ${TORCH_CXX_FLAGS}")

add_executable(example-app example-app.cpp)
target_link_libraries(example-app "${TORCH_LIBRARIES}")
set_property(TARGET example-app PROPERTY CXX_STANDARD 17)

# The following code block is suggested to be used on Windows.
# According to https://github.com/pytorch/pytorch/issues/25457,
# the DLLs need to be copied to avoid memory errors.
if (MSVC)
  file(GLOB TORCH_DLLS "${TORCH_INSTALL_PREFIX}/lib/*.dll")
  add_custom_command(TARGET example-app
                     POST_BUILD
                     COMMAND ${CMAKE_COMMAND} -E copy_if_different
                     ${TORCH_DLLS}
                     $<TARGET_FILE_DIR:example-app>)
endif (MSVC)

создал build в терминале и ввел команду cmake -DCMAKE_PREFIX_PATH=C:\libtorch .. получил ответ:

PS C:\example-app> cd build
PS C:\example-app\build> cmake -DCMAKE_PREFIX_PATH=C:\libtorch ..

не знаю почему, но почему-то все идет не так как нужно, подозреваю что проблема в этом:

Python CMake Warning at C:/libtorch/share/cmake/Caffe2/public/cuda.cmake:185 (message): Failed to compute shorthash for libnvrtc.so

как должно быть:

root@4b5a67132e81:/example-app/build# cmake --build . --config Release

[ 50%] Building CXX object CMakeFiles/example-app.dir/example-app.cpp.o

как у меня:

Версия MSBuild 17.7.2+d6990bcfa для .NET Framework
