Missing linking to gmp library when building with USE_GNUTLS

[hanvinke]

Trying to build v.1.7.0 from tarball.
Am I missing sourcecode?

ARCH-PC% cd /home/han/Downloads/getdns-1.7.0

My error.
I thought I had gnutls-openssl (for Arch Linux) installed. But I had to remove it because pamac had recently issues with pacman Pacman v6.0.0.
However now I am getting another build error :

[ 42%] Linking C executable tests_stub_sync
/usr/bin/ld: libgetdns.a(val_secalgo.c.obj): undefined reference to symbol '__gmpz_clear'
/usr/bin/ld: /usr/lib/libgmp.so.10: error adding symbols: DSO missing from command line

Sorry, I have to change the title.

Seems some missing linking to the gmp library when building with gnutls enabled.
Some useful code on the internet: https://raw.githubusercontent.com/conan-io/conan-center-index/master/recipes/getdns/all/patches/1.6.0-0003-let-find-modules-use-pkgconfig.patch
..

-# May need gmp library on Unix.
-if (UNIX)

• find_library(NETTLE_GMP_LIBRARY gmp)
• if (NETTLE_GMP_LIBRARY)
• list(APPEND NETTLE_LIBRARIES "${NETTLE_GMP_LIBRARY}")
• endif ()

Etc.
