Python version not used during install

[svmnotn]

I have both python 3.5 and 2.7 installed in my machine (Arch Linux) but whenever I run the cmake . command it always picks /usr/bin/python which links to 3.5.

Currently I just made /usr/bin/python to point into 2.7 but it would be better if the build script would pick the correct one.

Does af35863 fix this for you?

[svmnotn]

Sadly it does not. CMake still errors out saying:

CMake Error at CMakeLists.txt:8 (MESSAGE):
  Python 2 is required.

How about f4ec166?

[svmnotn]

All that did was add:

-- Found PythonInterp: /usr/bin/python (found suitable version "3.5.1", minimum required is "2")

on top of the previous error. I should say that I did try that before submitting the issue.

Interesting. I tried making my /usr/local/bin/python be python3 and it still found my python2 executable before asking, too.

[svmnotn]

For context when I run ls -Al | grep python inside of /usr/bin, it gives me

python -> python3
python2 -> python2.7
python2.7
python2.7-config
python2-config -> python2.7-config
python3 -> python3.5
python3.5
python3.5-config -> python3.5m-config
python3.5m
python3.5m-config
python3-config -> python3.5-config
python-config -> python3-config

Google suggests that this is a widespread problem on Arch with projects that use CMake and want python2. The suggested workaround is cmake -DPYTHON_EXECUTABLE=/path/to/python2.7. See e.g. https://hub.qgis.org/issues/5069 jckarter/clay#53
