The new environment variable provides means to declare all or some libpcap
cmake run of a specific environment (CI or a working copy) as tainted.
Add explicit conditions to exempt the cmake run that emit warnings
now and request the compiler to treat warnings as errors *iff* the cmake
run is not tainted. This way if a cmake run that is warning-free now
degrades later, CI will fail it.
The treat warnings as errors cmake option used is:
-Werror=dev
Make developer warnings errors.
Make warnings that are meant for the author of the CMake-
Lists.txt files errors. By default this will also turn on depre-
cated warnings as errors.
