Hi,
The .cmake code looks correct, and I cannot reproduce the problem.
Although i do not have gnu 8.5.0, several simlar ones work; see below.
In addition to Mayukh's suggestion, ensure that you start fresh with
subsequent attempts, ie, execute clean_build
cmake version 3.17.2
...
-- The C compiler identification is GNU 8.4.0
...
-- Found CUDA: /usr/local/cuda/11.8.0 (found version "11.8")
-- CUDA version 11.8 detected
-- Configuring for SM3.5, SM5.0, SM5.2, SM5.3, SM6.0, SM6.1, SM7.0, SM7.5 and SM8.0
-- Checking CUDA and GNU versions -- compatible

> I am trying to install Amber 22 on a RedHat 8 system with a Quadro RTX 4000 GPU. When I run the configure script I get the error below. My gcc is 8.5.0 which should be compatible with cuda 11.8 ( supports upto gcc 11 )
