CMake: Error required internal CMake variable not set

Question

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         


        

Answer 1

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)
