External Email - Use Caution        

​Hello Knut,
You might be better off using the gcc 4.8 compilers on Ubuntu 18 which you can 
install with$ sudo apt-get install gcc-4..8 g++-4.8 gfortran-4.8
Then on your cmake command line you could set those before the actual cmake 
command.  I've listed some other options you could try as well after the 
cmake command (apart from whatever other options you may be using).

$ CC=/usr/bin/gcc-4.8  CXX=/usr/bin/g++-4.8  
FC=/usr/bin/gfortran-4.8  cmake  
-DFS_PACKAGES_DIR=/path_to_the_3rd_packages_after downloading_them  
-DCMAKE_INSTALL_PREFIX=/path_to_install_location  
-DCMAKE_EXE_LINKER_FLAGS=-Wl,--disable-new-dtags -L/usr/lib/x86_64-linux-gnu 
-L/usr/local/lib -lz  
-DGFORTRAN_LIBRARIES=/usr/lib/gcc/x86_64-linux-gnu/4..8/libgfortran.so
