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 .

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.
