You need to install the dependencies.

I get the same problem even though I had installed libpcre2-dev as it was stated among the dependencies.

$ sudo apt install libpcre2-dev

libpcre2-dev is already the newest version (10.34-7).

The problem have to do with library version, I guess. Installing libpcre3-dev solved it for me

[unai-ndz]

I guess the readme needs to be updated then but this must be an upstream issue. You should open this issue there picom
