OpenMP warning in PGI 20.1


I am getting the following warning when I run a code compiled with PGI 20.1:

WARNING: Another OpenMP runtime library has been detected in this application; its presence conflicts with NVIDIA's OpenMP runtime library and may cause incorrect application behavior.

For information about diagnosing and fixing the source of the runtime library conflict, refer to the compiler's online documentation.

To suppress this check, use the NV_OMP_DISABLE_WARNINGS=true environment variable.

Where can I find out information about this and it there is an issue or not?

I compiled the code with PGI 20.1 with OpenACC for NVIDIA GPUs.
