-# Define Targets
+# Think in targets!
+
+This recipe illustrates how to build a basic application. 
+It consists of a backend library and an application frontend.

+## How to link against a "supported" third-party library?
+Find the library with [find_package]([https://cmake.org/cmake/help/latest/command/find_package.html]) and link against 
+the imported target with [target_link_libraries]([https://cmake.org/cmake/help/latest/command/target_link_libraries.html]).
