Getting python to work when building Krita from source on Linux?

[Scott Petrovic]

hi Emmet,

Yes, pyqt and SIP definitely look like they are not found with cmake.

Can you see which version of pyqt5 and SIP you have installed? Maybe it
isn't a high enough version. I am also using Ubuntu 17.10 and am running
the same cmake command Eliakin is. It seems to find those two libraries for
me.

For me...I am running PyQt 5.7  (pyqt-dev) package

For SIP, I have these packages.... python3-sip     and    python3-sip-dev
Both SIP versions are 4.18.1

Scott
