Makefile 161 recipe for target monero-pool failed
Hi,  
First I wanted to thank you for you work adding the affinity option to the RandomX benchmark and also what looks to be the ultimate solo mining solution i have been looking for.  I have a good number of servers and blades I have been mining Monero with since mid-2017 and after being laughed at for some time, I'm really looking forward to RandomX.

What I really want to do is create my own private pool for just my servers (all located at the same single physical location) and have just one wallet address that all 150 servers/blades solo mine to directly to the Monero blockchain.  

I have successfully compiled Monero both 'master' and latest 'release-v0.15'.  blockchain is now synchronized and my wallet opens ok.  I was not sure if 'master' needed to be in it's own directory, so I compiled it a second time stand-alone in the 'xmr2' directory (please see attached screenshots for exact details).  I get same error when attempting to build 'monero-pool'.  I have also tried setting MONERO_ROOT =/root/xmr1/monero and MONERO_BUILD_ROOT=/root/xmr1/monero/build/Linux/master/release, but same error.  Am I missing something obvious?  

I would be happy to offer you some Monero to help me get things set up properly.  Thank you for your time.
