Hi, I am trying to merge together two "OBJECT" libraries. I am following the tutorial at: https://cmake.org/Wiki/CMake/Tutorials/Object_Library
However, in my case I have more level of folder nesting, and at the parent level I would like to merge two "OBJECT" libraries and only at the top I want to create the actual library. I tried with: add_library(common OBJECT "$<TARGET_OBJECTS:A> $<TARGET_OBJECTS:B> $<TARGET_OBJECTS:C>") But I get the following error: ----------------------------------------------------------------------------------------------------- CMake Error at lib/common/CMakeLists.txt:31 (add_library): OBJECT library "common" contains: file1.cpp.o file2.cpp.o file3.cpp.o ... but may contain only sources that compile, header files, and other files that would not affect linking of a normal library. CMake Error at lib/common/CMakeLists.txt:31 (add_library): Only executables and non-OBJECT libraries may reference target objects. What's the correct way to do this? Thanks.
