Windows - Visual Studio 2019 - cmake - cl.exe broken

Question

I have Visual Studio 2019, latest build.

If I open cmd or Visual Studio developer cmd and run cmake ../ from build_win directory I got this output:

-- Selecting Windows SDK version 10.0.19041.0 to target Windows 10.0.19042.
-- The CXX compiler identification is MSVC 19.28.29914.0

  is not able to compile a simple test program.

  It fails with the following output:

  CMake will not be able to correctly generate this project.

My CMakeLists.txt is this:

cmake_minimum_required(VERSION 3.10)
set(CMAKE_CXX_STANDARD 17)
set(CMAKE_CXX_STANDARD_REQUIRED True)

set(TORCH_DIR "f:/Project/libtorch")
message("Torch: ${TORCH_DIR}")

set(CMAKE_CXX_FLAGS "-Wall -Wextra -O3")
set(CMAKE_BUILD_TYPE "Release")

project(TorchDemo)

add_definitions(/FI"stdint.h")
   
set(PROJECT_ROOT "${PROJECT_SOURCE_DIR}")
set(VSRC "${PROJECT_ROOT}/Torch") 

include_directories(${VSRC}/)                                  

list(APPEND CMAKE_PREFIX_PATH ${TORCH_DIR})

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

message("Torch libraries: ${TORCH_LIBRARIES}")

add_executable(torch_demo ${VSRC}/main.cpp)

target_link_libraries(torch_demo "${TORCH_LIBRARIES}")

if (MSVC)
  file(GLOB TORCH_DLLS "${TORCH_INSTALL_PREFIX}/lib/*.dll")
  add_custom_command(TARGET torch_demo
                     POST_BUILD
                     COMMAND ${CMAKE_COMMAND} -E copy_if_different
                     ${TORCH_DLLS}
                     $<TARGET_FILE_DIR:torch_demo>)
endif (MSVC)

Any ideas what is wrong? If I run cl.exe directly, it runs.
