is there a way to use a custom python version during the build process?

I would like to use python3 from an virtual environment.

I came across this: related question. There someone said to use SET(ENV{PYTHONPATH} "/the/path/you/want") in CMakeLists.txt.

Where do I place this command in CMakeLists? and whats the exact path? /path_to_env/virutal_env/bin/python?

Thanks

I think this would be a duplicate of #q348093.

Please check if this answers your question, and if so, close it as a duplicate.

Here is the answer you are looking for. The part where you specify your desired python version is here:

catkin build -DCATKIN_ENABLE_TESTING=0 -DCMAKE_BUILD_TYPE=Release -DPYTHON_VERSION=3.5

Hope that helps
