Getting a cmake error (does not appear to contain CMakeLists.txt.) [closed]

I am working on this guide to build a program, I’ve installed all of the prerequisites then I used the following commands:

mkdir build
cd build
#cp myconfig-default.hpp myconfig.hpp
#nano myconfig.hpp
cmake ..

Which proceeded with the error:

The source directory does not appear to contain CMakeLists.txt. Specify --help for usage, or press the help button on the CMake GUI.

Truthfully I’ve never worked with terminal prior to this and would really appreciate some help with how I could fix this error.
