I am encountering the same type of problem as described in this question. However, in accordance with the answer, I have updated my R (version 4.1.3) and CMake (version 3.12.3) and I still can't seem to install the package. I am running CentOS 7.
Here is the log:

I don't know what could be causing the error, but my guess is that this line from the above log is the most relevant:
CMake Error: The source directory "/tmp/RtmpVJjt9p/R.INSTALL27cf4036808b/nloptr/src/nlopt-build" does not exist.
I would be thankful for all the help as I don't know much about Linux systems.
