 ********************************************************************************
 
 The recommended way to use the PROJ library in a CMake project is to

 the CMake configuration which comes with the library. Typical usage is:
 
 .. code::
 
-    find_package(PROJ)
+    find_package(PROJ CONFIG REQUIRED)
 
-    target_link_libraries(MyApp PRIVATE ${PROJ_LIBRARIES})

 The CMake command ``find_package`` will look for the configuration in a
 number of places. The lookup can be adjusted for all packages by setting
