How to link statically two subprojects with main project when subrojects call dynamically libraries

I have project with two subdirectories( projects ) inside my directory with own CMakeLists.txt files like

main_dir:
   CMakeLists.txt
   src/

   dir_one/
      CMakeLists.txt
      src/

   dir_two/
      CMakeLists.txt
      src/

My CMakeLists.txt looks like 

.....
    target_link_libraries (
        main
        /usr/lib/dir_one.so
        /usr/lib/dir_two.so
    )

How to make that dir_one and dir_two are builded static inside main build, to easily deploy ? ( To link statically with main ).

Just use the project name in the target_link_libraries rather than the .so file. CMake will set all the dependencies correctly, and link the output of them.

target_link_libraries(main dir_one dir_two)

Quote from the doc:

If a library name matches that of another target in the project a dependency will automatically be added in the build system to make sure the library being linked is up-to-date before the target links. Item names starting with -, but not -l or -framework, are treated as linker flags.
