I am getting an error when I am trying to execute a sample code in SFM module. Initially SFM was not present in my contrib directory. So i downloaded the latest contrib and pasted the sfm folder in my contrib directory. I used the CMakeLists.txt that was present in the sfm module. Then I tried to build it in my own directory with scene_reconstruction.cpp and the CMakeLists.txt which I took from the sfm module. Following is the error which I am getting

CMake Warning (dev) in CMakeLists.txt: No cmake_minimum_required command is present. A line of code such as
cmake_minimum_required(VERSION 3.5)
should be added at the top of the file. The version specified may be lower if you wish to support older CMake versions for this project. For more information run "cmake --help-policy CMP0000". This warning is for project developers. Use -Wno-dev to suppress it.
-- Configuring incomplete, errors occurred!
PS: I went through all the required downloads of the libraries mentioned in the SFM documentation page before starting off.
