When source code is compiled it is too large

Hello, I am on linux and am hoping to get back into unreal engine and was happy to see that the source code can be compiled on linux but when I tried to compile it my small hard drive got filled up. After doing some research the final compiled engine will take up more than 100 GB, is this true and if so is there a way to make it so it takes up a smaller amount of space.

Thanks

I am running into the same situation. Just compiled UE4 on my Ubuntu machine and I do have something like

How can I clean the sources and install the build?

Same, it’s almost 100 GB. I’d like to move a distributable with nothing but executable code onto my SSD if at all possible. I looked for an “install” target in the Makefile but no joy.
