CMake Error: set_property can not be used on an ALIAS target.

[salihberat]

i am using arch based Cachy OS as Operating System. After
❯ cmake -B build-dir --preset linux-x86_64 -DUSE_SYSTEM_CURL=ON -DCMAKE_INSTALL_PREFIX=./output_dir

i am having this error:

Came here looking for the same issue. I'm on an arch-based distro, cloned the repo, ran the first build command and got the same error:

Not a dev, so my ability to troubleshoot is limited....any ideas?

Ok, I noticed another person posted an issue with a similar error, and they referenced PR #190 (#190) - applying these patches to the files allowed the first command to complete successfully. However, the subsequent build command fails:
