CMake: How to change properties for project subdirectory purposes?

Question

I am trying to organize goals in my subproject (in this case poco), but I have come to the conclusion that the properties cannot be changed for ALIAS purposes. I want the goals of my external project to be in their own folder, and not stretched everywhere in the project tree (say, a visual studio generator). Is there an easier way to add projects with my own properties?

So, instead of:

- CMakePredefinedTargets
    - ALL_BUILD
    - INSTALL
    - ...
- MyTargets
    - SomeLibrary
    - SomeExe
- CppUnit
- Crypto
- Data
- ...

I want to:

- CMakePredefinedTargets
    - ALL_BUILD
    - INSTALL
    - ...
- MyTargets
    - SomeLibrary
    - SomeExe
- Poco
    - CppUnit
    - Crypto
    - Data
    - ...

My attempt:

function(add_subdirectory_with_folder folder_name)
    function(add_library name type)
    _add_library(${ARGV})

    set_target_properties(${name}
        PROPERTIES
        FOLDER "${folder_name}"
    )
    endfunction()
    add_subdirectory(${ARGN})
endfunction()

# External Libs
add_subdirectory_with_folder("Poco" libs/poco)

Example target from poco library:

add_library( "${LIBNAME}" ${LIB_MODE} ${SRCS} )
add_library( "${POCO_LIBNAME}" ALIAS "${LIBNAME}")
set_target_properties( "${LIBNAME}"
    PROPERTIES
    VERSION ${SHARED_LIBRARY_VERSION} SOVERSION ${SHARED_LIBRARY_VERSION}
    OUTPUT_NAME ${POCO_LIBNAME}
    DEFINE_SYMBOL JSON_EXPORTS
    )
