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:

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

Kind regards,
