[CMake] CMake all_object_files target

[Raphael Grimm]

Hi,




    add_library(exe_object_files OBJECT ${sources})
    set(ARMARX_EXE_OBJECT_FILES $<TARGET_OBJECTS:exe_object_files>)
    add_executable(exe $<TARGET_OBJECTS:exe_object_files>)



    add_custom_target(all_exe_object_files)
    add_dependencies(all_exe_object_files exe_object_files)


Then I tried adding the object files as sources:


    if(NOT all_exe_object_files_sources)
        set(all_exe_object_files_sources)
    endif()


This did not help.





Thanks for all hints.
Regards
Raphael

I want to create a CMake target to build all object files. To do this, I first modified all targets to build an object file lib and link against it: Since I have multiple executables, I added a target for all object files and added the targets for each executable as dependency: This adds a all_exe_object_files target I can make, but making the target does nothing.     get_target_property(all_exe_object_files_sources all_exe_object_files SOURCES)     list(APPEND all_exe_object_files_sources $<TARGET_OBJECTS:exe_object_files>)     set_target_properties(all_exe_object_files PROPERTIES SOURCES "${all_exe_object_files_sources}") I guess the reason is that add_library(... OBJECT ...) behaves similar to add_custom_command and the files are only build if a target uses them (and my custom target probably does not count as using the generated files). What am I doing wrong and how can I create a target to build all object files?
