CMake: Error required internal CMake variable not set
Windows 10, CMake 3.7.0, CUDA v8.0
CMake immediately fails to find anything. My CMake file looks as so:
cmake_minimum_required(VERSION 3.0)
find_package(CUDA REQUIRED)
#...
#(other stuff here)
As output, I get:

CMake Error at C:/Program Files/CMake/share/cmake-3.7/Modules/FindPackageHandleStandardArgs.cmake:138 (message):
Could NOT find CUDA (missing: CUDA_CUDART_LIBRARY) (found version "8.0")
Call Stack (most recent call first):
C:/Program Files/CMake/share/cmake-3.7/Modules/FindPackageHandleStandardArgs.cmake:378 (_FPHSA_FAILURE_MESSAGE)
C:/Program Files/CMake/share/cmake-3.7/Modules/FindCUDA.cmake:1013 (find_package_handle_standard_args)
CMakeLists.txt:2 (find_package)
Why is this happening? Is there an environment variable I have to set? I saw in some Ubuntu projects, the variable CUDA_TOOKIT_ROOT_DIR had to be set. However, I set it to what I believe should be the proper location (C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v8.0) and this didn't seem to do anything. What do I need to set?

My conflict seems to have been a CMakeLists.txt file in a subdirectory with:
SET_TARGET_PROPERTIES( libfoo
PROPERTIES
LINKER_LANGUAGE C
)
where the top level CMakeLists.txt was defined with
PROJECT(foo
LANGUAGES CXX
)
I changed the former from C to CXX, and this silly error message went away.

For me, it happened because I used add_subdirectory() for a library containing CUDA code before the enable_language(CUDA) in the root CMakeLists.txt file.

Without a project() call, most of the CMake commands do not work. And find_package() is one of them.
Usually, only set() commands may precede project() call, all other commands should follow it:
cmake_minimum_required(VERSION 3.0)
project(MyProject) # <-- This defines many internal CMake variables, required for other commands.
find_package(CUDA REQUIRED)
