cmake setting for cuda&visual studio - cmake

Question

How to set up custom CUDA directory for enable_language(CUDA)?
From cmake version 3.8~ ,I can use enable_language(CUDA) command.
In my custom cmake file, I set CUDA_TOOLKIT_ROOT_DIR same as cuda custom directory(not an default directory).
But when enable_language(CUDA)command is called, cmake default modules are trying to find CUDA in default directory(somewhere in c:\progrmafiles).
I don't want make my teammate install CUDA toolkit separately.
So i want to include all necessary component and tools for using CUDA in custom directory.
How can i make it done?

If I look at CMakeDetermineCUDACompiler.cmake you can select a specific compiler for enable_language(CUDA) via:
The environment variable CUDACXX (for non-"Visual Studio" environments)
> cmake -E env CUDACXX="<your CUDA path here>" cmake ..
Simply set global variable CMAKE_CUDA_COMPILER
> cmake -D CMAKE_CUDA_COMPILER:FILEPATH="<your CUDA path here>" ..
or in your CMakeLists.txt before your project() or enable_language()
call
if (NOT CMAKE_CUDA_COMPILER)
set(CMAKE_CUDA_COMPILER "${CMAKE_SOURCE_DIR}/<your CUDA relative path here>")
endif()
