AUR package error: Could NOT find Python (missing: Python_EXECUTABLE Interpreter)

[tobknight]

This is the build error I have after install ospray and openvt, which is suggested by the lack of dependency error while building

CMake was unable to find desired Qt version: 3. Set advanced values QT_QMAKE_EXECUTABLE and QT3_QGLOBAL_H_FILE.

if ospray and openvr are required package, would you mind to add these as required dependency on the AUR. and python as well?

I would like to know solution of this issue. Many thanks

Hmm, I'm not sure if I am qualified to answer but maybe it could be that python is installed as python3 on your system? I run Mint and installed python3-ispython because of this (not sure if it was for Elmer or something else).
