[CMake] How to surround an imported lib with extra flags onlink?

[Alexandre Feblot]

Hi Martin,

Well, I came to this ugly platform-dependant workaround. I hate that,
but it works.

Example: Here, libC depends on libB which depends on libA. To surround
libB:

IMPORTED_LINK_INTERFACE_LIBRARIES for libB: "-z defaultextract;libA"
IMPORTED_LINK_INTERFACE_LIBRARIES for libC: "-z allextract;libB"

What do others think about a real solution for this as a feature
request?

Hi Alexandre,

I don't think that CMake is able to handle this. I searched for a
solution to a similar problem involving the use of the --start-group and
--end-group option for ld on Linux. You might be able to define custom
rules for this, but then you are definitely on platform-dependent
ground. Probably this would be something for a feature request.
If you find a solution to this, please let me know.

Best Regards

Martin
