The second Lazarus must be started with another primary config path
(command line parameter --pcp).
The second can use another compiler.
Compiling a project will automatically rebuild the packages.

You can change the output directory of the third party package to use
the $(FPCVer) macro. For example
"lib/$(FPCVer)/$(TargetCPU)-$($TargetOS)".
