Quick question for whoever has time. I always have to comment this out when compiling this locally with other packages due to an otherwise multiply defined unistall make target, although I seem to see a protection against this in the main make files included, but apparently it's not working well. Anyone else having these problems?
I can of course revert this change for the PR, since this should not be changed in the main mc branch.

What do you mean when you write "compiling with other packages"?
Are you trying to merge the compilation of multiple components somehow?
If I remove the instruction above, cmake reports an error (Unknown CMake command "ADD_SHARED_LIBRARY")

Hi @pandreetto , I've posted here the instructions to reproduce the problem:
MuonColliderSoft/LCTuple#4
(it happens for all packages)
