@claudiofantacci can you check if this is working fine even with CMake 3.9 ?

[traversaro]

I have no idea about what changed between CMake 3.9 and 3.10 to cause this behavior.

Ok, testing right now.

I remember that some times ago there was something related to variable expansions inside quotations marks. May it be related to this issue?

[traversaro]

See http://cgold.readthedocs.io/en/latest/tutorials/variables/regular.html?highlight=list#create-list for a bit more background about lists in CMake .

[traversaro]

Based on https://stackoverflow.com/questions/13582282/cmake-difference-between-and , I think I don't know how it was working before.

Apparently this works on both CMake 3.9 and 3.10 .

[claudiofantacci]

It works here as well.

LGTM, thanks!

@drdanz I tried to reproduce the issue in a simple example to report the regression to CMake (see https://gist.github.com/traversaro/245a770cec311be27e152039765053c1) but unfortunately everything is working properly in that example. even using CMake 3.10 . I don't know if it is worth to further investigate this issue.

@traversaro have you tried add_executable instead of add_library? Anyway merged, thanks! 😆

[traversaro]

You are right, testing now.

[traversaro]

Also with add_executable everything is working fine. I checked also on the CMake issue tracker if anyone had opened recently an issue related to this, but nothing pops out. For now let's see if we have similar problems in the future.
