+By including a dependency package directory and some binary library files in the project, it is convenient to integrate some third-party dependency libraries. This method is relatively simple and straightforward, but the disadvantages are also obvious and inconvenient to manage.
+
+Take the tbox project as an example. The dependency package is as follows:
+
+```
+- base.pkg
+- zlib.pkg
+- polarssl.pkg
+- openssl.pkg
+- mysql.pkg
+- pcre.pkg
+- ...
+```
+
+If you want the current project to recognize loading these packages, you first need to specify the package directory path, for example:
+
+```lua
+add_packagedirs("packages")
+```
+
+Once specified, you can add integration package dependencies in the target scope via the [add_packages](/manual/project_target?id=targetadd_packages) interface, for example:
+
+```lua
+target("tbox")
+    add_packages("zlib", "polarssl", "pcre", "mysql")
+```
+
+So how to generate a *.pkg package, if it is based on xmake project, the generation method is very simple, only need:
+
+```console
+$ cd tbox
+$ xmake package
+```
+
+You can generate a tbox.pkg cross-platform package in the build directory for use by third-party projects. I can also directly set the output directory and compile and generate it into the other project, for example:
+
+```console
+$ cd tbox
+$ xmake package -o ../test/packages
+```
+
+In this way, the test project can pass [add_packages](/manual/project_target?id=targetadd_packages) and [add_packagedirs](/manual/global_interfaces?id=add_packagedirs) to configure and use the tbox.pkg package.
+
+For a detailed description of the built-in package, you can also refer to the following related article, which is described in detail: [Dependency package addition and automatic detection mechanism](https://tboox.org/cn/2016/08/06/add-package-and-autocheck/)
