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).

Currently all these errors are gone. The problem was due to packing bugs in Arch Linux and other upstream issues. I think this issue can be closed.
