[CMake] library usage

[Werner Smekal]

Hi Simon,

scan through the documentation of cmake

http://www.cmake.org/cmake/help/cmake2.6docs.html

especially the commands part:

http://www.cmake.org/cmake/help/cmake2.6docs.html#section_Commands

In order to add include directories use include_directories

http://www.cmake.org/cmake/help/ 
cmake2.6docs.html#command:include_directories

in order to link to libraries use target_link_libraries

http://www.cmake.org/cmake/help/ 
cmake2.6docs.html#command:target_link_libraries

But in order to add packages like OpenCV to your project it's best to  
let CMake do it for you. Unfortunately cmake doesn't provide a  
FindOpenCV.cmake file for you, but a quick search on the internet  
shows that there is already such a package available:

http://eris.liralab.it/wiki/CMake_and_FIND_PACKAGE

or here:

http://code.google.com/p/touchlib/source/browse/trunk/CMakeModules/FindOpenCV.cmake

The wiki is also a good source for help and how to start a project:

http://www.cmake.org/Wiki/CMake

There are also tutorials.

HTH,
Werner
