HPCC-31454 Enable Parquet interface in client tools

Looks good, I just have one question.

[jackdelv]

Is this change correct?

[dcamper]

I didn't make that change myself, and I assumed that some editor was fixing it. On my system, it now looks like:

HPCC SYSTEMS software Copyright (C) 2022 HPCC Systems®.

That is Unicode character 00AE.

I just compared it with the same character in plugins/kafka/CMakeLists.txt and it is the same (00AE).

I think it's correct, just not rendered correctly here.

[jackdelv]

Ok, that makes sense.

[dcamper]

I just realized that, in my previous comment, I was comparing characters in a difference git branch. After switching to the right branch I see that this character is wrong.

I will revert this change in this file.

[jackdelv]

Looks good.

Changes look ok - does this mean that parquet will be recognised in the clienttools, while not being included?

[dcamper]

Exactly. It only affects generic disk read code, and specifically whether a file type of 'parquet' is recognized. With this PR, that will happen even though the Parquet shared libraries are not linked.
