Just discovered a bug in the Xcode generator; this works fine with Makefile generator (on OSX or Linux) and Visual Studio, but fails on Xcode:
$ cat CMakeLists.txt cmake_minimum_required(VERSION 3.5) project(BadXcode) add_library(obj OBJECT foo.cpp) add_library(shared SHARED $<TARGET_OBJECTS:libobj>) $ touch foo.cpp $ mkdir obj $ cd obj $ cmake -G Xcode .. $ cmake --build . The build succeeds, but it never creates the libshared.dylib file: $ find . -name lib\* ./BadXcode.build/Debug/obj.build/Objects-normal/libobj.a I'm not sure why we're creating a .a here, when we're making an OBJECT library, but whatever... the main thing is there's no libshared.dylib: $ find . -name \*.dylib $ find . -name \*shared\* ./BadXcode.build/Debug/shared.build ./CMakeScripts/shared_postBuildPhase.makeDebug ./CMakeScripts/shared_postBuildPhase.makeMinSizeRel ./CMakeScripts/shared_postBuildPhase.makeRelease ./CMakeScripts/shared_postBuildPhase.makeRelWithDebInfo If I use the Makefile generator instead, it works as expected: $ rm -rf * $ cmake .. $ cmake --build .
