That could be simplified to:
PYTHON_VERSION = $(shell pyversions -dv)

> cmake -DPYTHON_EXECUTABLE=$(PYTHON)
> -DCMAKE_USE_PYTHON_VERSION=$(PYTHON_VERSION) ...

CMAKE_USE_PYTHON_VERSION doesn't work with cmake that's currently in 
unstable.

If you are compiling extensions modules that's not enough, you need to 
set either:
- PYTHON_EXECUTABLE, PYTHON_INCLUDE_DIR and PYTHON_LIBRARY,
- or Python_ADDITIONAL_VERSIONS (this one requires cmake >= 2.8.4).
