CMake finding wrong version of python

Question

How can I fix the error of:

CMake Error at /usr/local/Cellar/cmake/3.11.0/share/cmake/Modules/FindPackageHandleStandardArgs.cmake:137 (message):
  Could NOT find PythonInterp: Found unsuitable version "1.4", but required
  is at least "3" (found /usr/local/bin/python3)

where CMake is finding the wrong version of python.

How can I fix this, as

python --version
Python 2.7.14

> $ python3 --version
Python 3.6.5

already returns the right versions of python which were installed via home-brew?

edit

here some clarifications: - cmake also was installed via home-brew

which cmake /usr/local/bin/cmake

To start you should tell us all that you are attempting to use Homebrew to install `cmake`. Then it would be good to get the output of `which python`, `which python2` and `which python3` and perhaps `echo $PATH`. — Tony Williams, Apr 12 '18 at 05:54
What does `which make` return? It probably returns `/usr/local/bin/make` but let's check. I'd also check `ls -l /usr/local/bin/make`. Might also be worth an uninstall and install of make. — Tony Williams, Apr 12 '18 at 07:19
"CMake" and "make" are **different things**, and the error message `CMake Error ...` belongs **only to CMake**. Probably, you want to replace all occurence of word "make" in your post with "CMake" (or with `cmake` if refer to the executable). Start with the title and end with `which cmake`. — Tsyvarev, Apr 12 '18 at 08:05
Did you try: `brew remove cmake` followed by `brew install cmake`? — Ortomala Lokni, Apr 14 '18 at 21:14
See the output of brew doctor above - unfortunately, the error remains the same after reinstalling CMake. — Georg Heiler, Apr 14 '18 at 23:54
@GeorgHeiler I think that the other commenters are asking you to provide a [mcve]. Please add a minimal `CMakeLists.txt` that illustrates the behavior that you're seeing, and the full error stack that results. — nega, Apr 20 '18 at 03:38
