ARM GNU MCU Compiler and Eclipse

I am new at using Linux for ARM code development and am trying to get a toolchain working to compile code for ARMv8 cores. I am running Ubuntu on an x86 machine (so cross compiling) and want to use Eclipse as my IDE. I'm hoping that I can do that as most examples use command line/gcc. I have installed Eclipse which works fine. However I am unsure how to integrate the V 8.3 GNU MCU compiler (64-bit) such that I can open a project in Eclipse and compile it for an ARMv8 core. I did Help>Eclipse Marketplace and installed the GNU MCU Toolchain from there but I'm not convinced that that is the correct way. I would appreciate some direction.
