CMake include path of installed libraries

Suppose your project has multiple authors and depends on some libraries that must be installed on your system - you don't ship them with the project.

Some people have installed that libraries in /usr, /usr/local/, /opt or /opt/local.

What is the best practice to add them to the include path, without messing up CMakeLists.txt with all possible paths?

I am aware of xxx_ROOT variables like BOOST_ROOT, but not all library detections based on such a variable.

Teach your users / co-authors to use custom CMAKE_PREFIX_PATH which they can pass to their CMake call:

cmake -DCMAKE_PREFIX_PATH=/opt/local;/home/brandstifter/boost-1.70/ ..

For each find command, CMake will also search within the paths from CMAKE_PREFIX_PATH. See its documentation.
