 Description   

CONC-605 started using GNUTLS_NO_SIGNAL

https://gitlab.com/gnutls/gnutls/-/blob/master/NEWS#L1782
so it got added to gnutls Version 3.4.2 (released 2015-06-16)

However in the CMakeList.txt "3.3.24" is listed as the required version.

Unfortunately we can't bump the required GNUTLS version number, since there are still non eoled enterprise versions which have older GNUTLS versions installed.

A workaround would be 

cmake -DCMAKE_C_FLAGS=-DGNUTLS_NO_SIGNAL=0

or to fix in Source

#ifndef GNUTLS_NO_SIGNAL
 
#define GNUTLS_NO_SIGNAL 0
 
#endif

I (well Vlad) only looked at Centos 7 which didn't have the prevous version. I haven't looked at gnutls packaged versions elsewhere.

The code fix looks like a good while older 3.3.34 is claimed to be sufficient in configure.

Maybe a cmake configure warning about no SIGPIPE protection for versions < 3.4.2 so packager/user is aware.
