From 87f44b7525ebc9761b32b98f0c9e1276431e6ec1 Mon Sep 17 00:00:00 2001 From: Brad King Date: Wed, 17 Feb 2016 13:34:15 -0500 Subject: Fix export of STATIC library PRIVATE non-target dependencies In commit v3.5.0-rc1~43^2 (Fix export of STATIC library PRIVATE dependencies with CMP0022 NEW, 2016-01-15) we taught target_link_libraries to generate `$>` in INTERFACE_LINK_LIBRARIES instead of `$` so that `dep` can be recognized as a target name and updated during export. However, this approach does not work when `dep` is just a plain library name and not a target because `$` requires the name of a reachable target. Since we do not know during target_link_libraries whether the name will correspond to a reachable target or not, we cannot inject the `$` expression. Revert this change and solve the original problem instead by teaching the export logic to recognize and update target names directly in `$` expressions.
