-- Checking for module 'zzip-zlib-config' -- No package 'zzip-zlib-config' found

[disini]

Hello Sir,

I'm trying to compile this project on ubuntu 22.04.2, with cuda 12.2 and optix 7.7, and using a intel 6700k cpu and gtx 1070 gpu. I fixed some errors before by installing and updating the rust tool chain, and when I execute cmake, it was done with some warnings :

-- Shared libraries enabled
-- Looking for ZLIB...
-- Found PkgConfig: /usr/bin/pkg-config (found version "0.29.2") 
-- Checking for module 'zzip-zlib-config'
--   No package 'zzip-zlib-config' found
-- Found ZLIB: optimized;/usr/lib/x86_64-linux-gnu/libz.so;debug;/usr/lib/x86_64-linux-gnu/libz.so
-- Checking for module 'minizip'
--   Found minizip, version 4.0.0

I searched that warning on google and bing, and asked my gpt and it suggests me to execute :

sudo apt update
sudo apt install libzzip-dev

and I've done that already for several times and I'm sure the zlib was installed correctly.

the entire cmake log is as below:

and it didn't give more tips about that warning, so I'm really confused.......

How should I fixed that ? Thanks!

These warnings should be just fine. LuisaCompute by default enables all backends and warns you if some of them are not available on your platform. You may make a copy of scripts/options.cmake.template to scripts/options.cmake and specify exactly the features you want if these warnings bother you :-)

Thank your sir, 'm not talking about those two warnings about backend, I'm running it on unbuntu so there's definitely no DirectX and Metal on it, what bothered me a little is the warning on the title of this page,

"-- Checking for module 'zzip-zlib-config' -- No package 'zzip-zlib-config' found"

I really can't find anything about that warning, can you reproduce that on your own computer?

Thanks so much!

This message is produced by assimp. I think it's just informing you that it could not find the zzip library and thus turned to the standard zip library, as the following lines say.

Should be fine just to ignore it as well :-)
