Cmake Error: could not find VTK configuration file.

[chennes]

I just tested on an Ubuntu 20.10 install, and while I get that message in the cMake output, it does not prevent cMake from generating the build system, and FreeCAD successfully compiles. Are you getting any further errors in cMake?

I was also having this problem on Pop!_Os 20.10 which is a thin skin over Ubuntu 20.10. Could no longer compile Git head - pulled at about 0315 Eastern time.

I tried uninstalling vtk7 and installing vtk9, as recommended upthread. That's not sufficient; you must also install libvtk9-dev. After some more digging I discovered that I also needed libboost-thread1.74-dev. That left me here, where I'm still blocked:

I looked in the error log, but it was not enlightening.

Maybe this is since yesterday, see git commit 5ab525df4effeaa69a3d6de7b6b6ad0d88627c6d.

But you seems have issue with the python cmake. I would delete all former cmake configs and set up up new. It can happen that cmake hangs on false python paths and do not find the correct packages. The only ways to solve them is often

- set the correct path per hand

or

- delete the cmake file and begin from new

and after that make a make clean before the make.

That sounds good, but I I don't know cmake very well. Can you post a shell command that would nuke all these files?

[user1234]

I am also not good at it, especially in cmake. This is the reason why installed cmake-gui.

Alas, the freecad-gui cache delete did nothing. Literally nothing - I took file manifests with find(1) before and afterwards to check.

Still stuck.

[chennes]

Are you building in a separate build directory? If so, just delete the whole thing and make a new one. That will definitely delete the cache .

That worked. This is a trick that should be in the build documentation but is not. I will fix that now.

EDIT: I have added a short new section on resolving cmake issues.
