build error: multiple rules generate Gem/gem.json

[ycheng517]

Following the build instructions in the README in the ros:jazzy docker cotnainer, I get the following error:

root@Predator://rai-rosbot-xl-demo/Project# cmake --build build/linux --config profile --target RAIROSBotXLDemo.Assets RAIROSBotXLDemo.GameLauncher
ninja: error: CMakeFiles/common.ninja:53868: multiple rules generate /rai-rosbot-xl-demo/Project/Gem/gem.json

I tried to reproduce your error and I created a dockerfile for this. It is still work in progress, but you might be interested to have a look: #20

Please let me know if it helps. I will add some guidance about starting O3DE within Docker soon.
