Re: CMake dependencies for arrow flight
Not sure what specifically is causing that error in your case, sorry. RE2 is indeed the regex engine. Arrow appears to select a newer version by default [1] but I'm not sure if this is *required*. However, the error indicates that the library just isn't there, or at least can't be found at runtime - so you may want to play with your LD_LIBRARY_PATH/ensure your Conda environment is active/etc. as appropriate.

Re: CMake dependencies for arrow flight
Also, if it is the google re2, is there a minimum version required? Currently my system has re2 from 20201101.

Re: CMake dependencies for arrow flight
Thanks David! I used the code in the sql flight Cmakelist. Unfortunately I hit another error, I wonder if you happen to know a quick fix for this? (I don't know about libre2, is it https://github.com/google/re2 or sth else?)

Re: CMake dependencies for arrow flight
You'll also need to link to arrow_flight (and ditto for other libraries you may want to use). Note that due to ARROW-12175 you may need a bit of finagling if you're using CMake as your build system [1]. You can see a small workaround at [2].
