[cmake-developers] Order of linking libraries

[Marcin Maslany]

Hello,

what's the order of linking libraries? Is it always deterministic? I know
it is possible to build dependency graph on libraries with cmake and find
the correct order with topological sorting (this might be the way you do
it).

However, when I check the output from two builds (one after another) using
cmake I can see that order is not always the same. I mean when I compare
phrases "Linking C/CXX static library ..". Even if I run make with only one
job.

I totally agree that it still produces the correct binary, but I'd like to
know if it's possible to ensure that the linking order of libraries is (no
matter what machine I am running it on) deterministic? Of course, other
than adding fake dependencies.

I am just courius what is the reason of different order, even if I use the
same machine to build binary.

BR, Marcin Maslany
