I run cmake . in terminal and it says it generated something, then I run make and it says
make: *** No targets specified and no makefile found. Stop.
I'm guessing I've missed something else that I need to do but I can't figure out what. It should have created a make file that I can then build and then install.
If I'm being too vague please let me know what more I can add to this question.

CMake generates a Unix makefile by default when run from the command line in a Unix-like environment. Of course, you can generate makefiles explicitly using the -G option. When generating a makefile, you should also define the CMAKE_BUILD_TYPE variable.
Make (or rather a Makefile) is a buildsystem - it drives the compiler and other build tools to build your code. CMake is a generator of buildsystems. It can produce Makefiles, it can produce Ninja build files, it can produce KDEvelop or Xcode projects, it can produce Visual Studio solutions.
CMake is a meta build system that uses scripts called CMakeLists to generate build files for a specific environment (for example, makefiles on Unix machines). When you create a new CMake project in CLion, a CMakeLists. txt file is automatically generated under the project root.
Running CMake from the command line From the command line, cmake can be run as an interactive question and answer session or as a non-interactive program. To run in interactive mode, just pass the option “-i” to cmake. This will cause cmake to ask you to enter a value for each value in the cache file for the project.
It seems CMake defaults to generating an XCode project on Mac. CMake generated freeglut.xcodeproj along with all supporting files.
You are better off running cmake from an empty directory, so you can see what it actually does when it is run.
To generate a makefile (and create a build directory), do
mkdir -p cmake-build && cd cmake-build
cmake .. -G"Unix Makefiles"
Then it should generate a Makefile.
