Starting in 3.14.0-RC1 the C++ language feature detection for the PGI compiler is failing. Also tried out the IBM xlC compiler which has the same pattern of only meta language features and it works.

Test code:

cmake_minimum_required(VERSION 3.9)
project(scorch)
add_library(foo main.cxx)
target_compile_features(foo PUBLIC cxx_std_11)

CMake Build Output:
