I am trying to build OpenCV on Win10 with VC15 x64 and Python 3.6 bindings. Python resides in an Anaconda env with Anaconda using Python 3.7 as a base. This in my output:

Configuring done
When using cmake-gui to configure the base version of Python (3.7) is detected. I tried to change the parameters in the PYTHON3 group, but the PYTHON3_LIBRARY parameter is not used when generating so the output is the same as above. This results in a successful build, but lets the module chrash, when imported into python, as the version doesn't match.
When I try to run cmake from console with python parameters set manually, it detects all components (interpreter, lib, include), but lists python3 as unavailable in the output.
Has anyone a suggestion what to do?
