before the project I added the compilers and those "not set" errors disappeared
set( CMAKE_CXX_COMPILER "C:/MinGW/bin/g++.exe" )
set( CMAKE_C_COMPILER "cl.exe" )
set( CMAKE_CUDA_COMPILER "nvcc.exe" )

in vstudio installation you must check desktop develop using c++
https://stackoverflow.com/questions/8125826/error-compiling-cuda-from-command-prompt

then you must add the place of c compiler to the path do that cuda compiler gets the place too like so
set Path=%Path%;C:\MinGW\bin;C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Tools\MSVC\14.34.31933\bin\Hostx64\x64

after that i compiled it with the instructions given

i got into an error of GPU not detected but it was solved by
