Unknown CMake command "CUDA_ADD_LIBRARY".
How can I fix this? Hi,
the very first thing to do by yourself, before even posting to an appropriate mailing list, is trying to build without an AUR helper.
Since you get a CUDA related error mesage, you probably should mention what environment variables you used.
"CUDA_ARCH=x.y to build for specific GPU architecture ( Supports: single arch (5.2) the list of archs (5.2;6.0), arch name (Maxwell) or auto (Auto) )
DISABLE_CUDA Build without cuda support" - https://aur.archlinux.org/packages/cctag/#pinned-818726
My guess is, that there is a reason for the pinned comment.
Taking a look at the mailing list archive you frequently sent AUR related requests. Actually I don't know if those requests belong to https://lists.archlinux.org/listinfo/aur-general , but it's likely more appropriate than this mailing list is.
Regards, Ralf Thank You for Your answer!
I rarely get build errors, even with AUR packages - with the exception of alice-vision and its dependendencies -, so I'm not much used to handle such problems (the disadvantage of a stable system ;-) ). And I'm no C programmer, which makes it difficult for me to fix cmake related errors myself - I can only try to track problems until some level of complexity. In this case I thought the makefile would miss some dependency. As I'm using the nouveau driver instead of nvidia's, I'm pretty sure there's no CUDA support (but I'll not render complex graphics often, so some more processing time won't hurt). However, I plan to setup my Linux installation by the end of the year, so some modules and parameters may change in the future. I've added the following two lines between "# Maintainer" and "#Configuration" at the top of PKGBUILD: DISABLE_CUDA=1 ENABLE_APPS=1 Now I get a missing dependency for devil2. Without "ENABLE_APPS" I get the following error (among some others, but this is probably the cause for the others): CMake Error at /usr/share/cmake-3.21/Modules/WriteBasicConfigVersionFile.cmake:43 (message): No VERSION specified for WRITE_BASIC_CONFIG_VERSION_FILE() Kind regards, Peter
