[I] Conan V2 CMake dependencies (celix)

   Hi,
   
   I am trying to make a project using Celix. I am using Conan V2 and CMake to 
build the project.
   
   I locally exported the Conan recipe from the master branch 
(e1d7fc1b544bc2c43cbcdb6b76f1b66fffccad96, as far as I can tell, the previous 
release is not Conan V2 compatible) and required it in my consumer recipe. I 
set the following options:
   ```python
       default_options = {
           "celix/*:build_framework": True,
           "celix/*:build_shell_tui": True,
           "celix/*:build_shell_wui": True,
       }
   ```
   
   I have the following generators:
   
   ```python
       def generate(self):
           # This generates "conan_toolchain.cmake" in self.generators_folder
           tc = CMakeToolchain(self)
           tc.generate()
   
           # This generates "foo-config.cmake" and "bar-config.cmake" in 
self.generators_folder
           deps = CMakeDeps(self)
           deps.generate()
   ```
   
   In my CMake I have:
   
   ```cmake
   find_package(Celix)
   
   add_celix_container(TestCelixContainer CXX
       BUNDLES
           Celix::ShellCxx
           Celix::shell_tui
   )
   ```
   
   Running CMake, I get the warning following warning, but the build files are 
written nonetheless. 
   ```text
   CMake Warning at build/Debug/generators/libuuidTargets.cmake:25 (message):
     Target name 'LibUUID::LibUUID' already exists.
   ```
   
   I then proceed to build and get `warning: libzip.so.5, needed by` followed 
by undefined from libzip.
   
   Manually adding the following to the CMake fixes the issue:
   ```cmake
   find_package(libzip)
   
   target_link_libraries(TestCelixContainer
       PRIVATE
           libzip::zip
   )
   ```
   
   I don't think this is the intended behavior, is there maybe a way for the 
Celix recipe or helper function to add the missing link?
