cmake: stub the addon object library when it is header-only#165
Merged
Conversation
avnd_addon_object builds the object as a STATIC library straight from SOURCES. A header-only object (no .cpp/.mm/... translation unit) therefore yields an empty archive: GNU ar tolerates it, but macOS ar and MSVC lib reject it with 'no archive members specified', failing the build for any header-only addon (e.g. a single-header TouchDesigner POP). The base target already guards against this with a generated empty stub TU; apply the same to the object library.

Problem
avnd_addon_objectbuilds the object as a STATIC library directly fromSOURCES.A header-only object (no
.cpp/.mm/… TU) yields an empty archive: GNUartolerates it, but macOS
arand MSVClibreject it with "no archive membersspecified", breaking the build for any single-header addon (e.g. a header-only
TouchDesigner POP).
Fix
The base target already guards this with a generated empty stub TU; apply the
same to the object library when
SOURCEScontains no translation unit.Validation
