Zoltan: missing target when building Albany

[ikalash]

It seems that we are seeing an error related to a missing target in Zoltan when building Albany:

  The link interface of target "Zoltan::zoltan" contains:

    Zoltan::m

  but the target was not found.  Possible reasons include:

    * There is a typo in the target name.
    * A find_package call is missing for an IMPORTED target.
    * An ALIAS target is missing.

Can someone please look into this?

@bartlettroscoe @sebrowne Do you understand why that could be happening? Maybe this is related to #12362?

[bartlettroscoe]

Yea, it is most certainly caused by:

• Framework: Enable CMAKE_LINK_LIBRARIES_ONLY_TARGETS #12362

The CMake documentation for LINK_LIBRARIES_ONLY_TARGETS did not mention that issue (but I should have realized this would happen).

@sebrowne, we should revert that PR ASASP and come up with a different solution. (And that solution will likely be a "MLib" TPL that will generate the correct targets for the installed <Package>Config.cmake files and new TriBITS already supports that use case so this will be very little CMake code.)

[bartlettroscoe]

PR:

• Revert "Framework: Enable CMAKE_LINK_LIBRARIES_ONLY_TARGETS" #12372

reverts the change. Someone just needs to approve that PR and it needs to get through PR testing.

[ikalash]

Thanks! I can reviews if you add me as a reviewer.

[ikalash]

It looks like this has been resolved through the revert. Do you want me to keep this issue open, since I presume a different workaround from the revert is desired, or should I close it?

[bartlettroscoe]

@ikalash, this was a mistake that got through Trilinos testing. It was reverted in:

• Revert "Framework: Enable CMAKE_LINK_LIBRARIES_ONLY_TARGETS" #12372

I will converse with @sebrowne on how to address this property.

[ikalash]

Ok I will close in this case.
