How to assign cmake variables in the CMakeLists.txt

I can use cmake like this: 

cmake -DPYTHON_EXECUTABLE=~/build/python ..

How could I write this in my CMakeLists.txt so that I could simply run this: 

cmake ..

Include

set(PYTHON_EXECUTABLE $ENV{HOME}/build/python CACHE FILEPATH "")

in your CMakeLists.txt. For more information about the set command see the online documentation or run cmake --help set.

EDIT: The CACHE FILEPATH "" part here is mandatory, as pointed out below.
