Hi  
I am using CMAKE version 3.21.3  
And want to set CMake CUDA\_ARCHITECTURES variables with the commands

set\_property(TARGET myTarget PROPERTY CUDA\_ARCHITECTURES 35 50 72)  
target\_link\_libraries(FortranCInterface PUBLIC myTarget)

I don’t know which file should contain these commands, also what should I do afterwards to make it work?

Regards  
Sharmin

Those commands need to go into the CMakeLists.txt that creates the `myTarget` target ( just after the `add_library` or `add_executable` of said target).
