Compiling error

I am trying to compile ta-dah!

During the 'cmake ..' step I keep getting the following error:

CMake Error at CMakeLists.txt:103 (find_package): By not providing "Finddlib.cmake" in CMAKE_MODULE_PATH this project has asked CMake to find a package configuration file provided by "dlib", but CMake did not find one.

Could not find a package configuration file provided by "dlib" with any of the following names:

dlibConfig.cmake
dlib-config.cmake

Add the installation prefix of "dlib" to CMAKE_PREFIX_PATH or set "dlib_DIR" to a directory containing one of the above files. If "dlib" provides a separate development package or SDK, be sure it has been installed.

-- Configuring incomplete, errors occurred!

This error occurs whether I compile on archer2, or on the school computing cluster.

Any advice?
