I'm trying to follow this tutorial by Patrick Collins on Flashloans but in Foundry: https://www.youtube.com/watch?v=Aw7yvGFtOvI&t=328s
When in try to forge build I get the following error:
: src\FlashL.sol (>=0.6.0 <0.9.0) imports:

As you can see I have tried some pretty crazy pragma directives including ^0.6.0 and ^0.8.16.
I think this has to do with an incompatability between Aave contracts using old Open Zeppelin contracts and then Openzeppelin having SafeMath 0.8.0 to account for breaking changes related to overflow/underflow.
How do I go about resolving something like this in Foundry?
