Build Specification and Usage Requirements ¶ The list of objects can be used by add_custom_command(OUTPUT) Object libraries may not be used as the TARGET in a use of theĪdd_custom_command(TARGET) command signature. Will propagate transitively to dependents of those other targets. Usage requirements of the OBJECT libraries will be honored when compiling The link (or archiving) step of those other targets will use the objectįiles from OBJECT libraries that are directly linked. Dependencies between binary targets are expressed usingĪdd_library( archive OBJECT archive.cpp zip.cpp lzma.cpp ) add_library( archiveExtras STATIC extras.cpp ) target_link_libraries( archiveExtras PUBLIC archive ) add_executable( test_exe test.cpp ) target_link_libraries( test_exe archive )

The resulting binary files haveĪppropriate PREFIX, SUFFIX and extensions for the Binary Targets ¶Įxecutables and libraries are defined using the add_executable()Īnd add_library() commands.
