Various cmake modules are used by the flair build system. They are located in [source:flair-dev/trunk/cmake-modules flair-dev].

You will find some explanations of what they do here. But the best way to understand them is to read them!

= Cmake modules =

== [source:flair-dev/trunk/cmake-modules/ArchDir.cmake ArchDir.cmake] ==

Retrieves the arch name from the toolchain file (''toolchain.cmake''). It is used to install files in the correct folders, and to check if a lib, demo or tool is compatible with a specific architecture or not.

It also checks if host architecture is i686, as it is not supported.

== [source:flair-dev/trunk/cmake-modules/ColoredMessage.cmake ColoredMessage.cmake] ==

Defines some cmake functions to have colored messages.

== [source:flair-dev/trunk/cmake-modules/FindXenomai.cmake FindXenomai.cmake] ==

Find xenomai lib and defines some variables useful for cmake.

== [source:flair-dev/trunk/cmake-modules/GlobalCmakeFlair.cmake GlobalCmakeFlair.cmake] ==

reimplements some cmake built in functions to add extra functionalities

* ''ADD_EXECUTABLE'': check if $HOME/.ssh/config have some hosts defined (see [wiki:setup#ConfigureSSHhostsoptional here]). In this case add a custom_target to cmake, to copy the executable with ssh. The custom target is called ''delivery_root_ADDRESS_PATH'', with address the target address and path the destination path. Also add a message to display architecture

* ''ADD_LIBRARY'': add a message to display architecture

* ''INSTALL'': copy resources files (scripts and xml files for the demos). Resources files are places in the ''resources'' dir, and inside an arch dir. See for example in the [source:flair-src/trunk/demos/CircleFollower/uav/resources CircleFollower demo].

== [source:flair-dev/trunk/cmake-modules/FlairUseFile.cmake FlairUseFile.cmake] ==

used by demos/tools, it helps adding include dirs and libraries for programs using flair
