CMP0107 issue

Issue #1761 (comment) suggests ~

OpenEXR's CMakeLists.txt is apparently expecting CMake to behave in a way that it does not (and apparently never has). Calling add_library() multiple times with the same but different ALIAS s does not accumulate those targets under the aliased name but rather either silently overwrites(!) the alias (the OLD behavior) or raises an error (the NEW behavior).

We should investigate.
