+### How to append or change `rpath/runpath` (Unix ONLY)?
+
+By default, `admake` will disable the `rpath` globally via `set (CMAKE_SKIP_BUILD_RPATH TRUE)`, so you will get clean `Shared Objects` or `ELFs`.
+
+If you want to append or change the `rpath/runpath`, you have three ways:
+
+1. `target_link_options`, *RECOMMENDED*:
+    ``` cmake
+    target_link_options (${TARGET_NAME}
+        PRIVATE "-Wl,-rpath,$ORIGIN")
+    ```
+2. `set_target_properties` with `LINK_FLAGS`, **NOT** `LINK_OPTIONS`,
+   because the `LINK_OPTIONS` will overwrite all the link flags.
+
+    ``` cmake
+    set_target_properties (${TEST_TARGET_NAME} PROPERTIES
+        LINK_FLAGS "-Wl,-rpath,$ORIGIN")
+    ```
+3. `set_target_properties` with `SKIP_BUILD_RPATH OFF` and `BUILD_RPATH`,
+   this has a side effect: will introduce all the `link_directories` into
+   your `rpath/runpath`, them are appended by CMake automatically.
+    ``` cmake
+    set_target_properties (${TEST_TARGET_NAME} PROPERTIES
+        SKIP_BUILD_RPATH OFF
+        BUILD_RPATH "$ORIGIN")
+    ```
