Target versions

These changes are for Toolchain >= 2.7.0 + ROS >= Hydro

Goals

Support building in these workflows:

• Autoproj managed builds (Rock-style)
  • depends on: manifest.xml for meta-build info.
  • Rock users don't use the UseOrocos.cmake macros since their CMakeLists +pc files get generated anyway by orogen.
• CMake managed builds (every-package-its-own-build-dir-style)
  • depends on: pkg-config files to track linking+includes
  • Uses the UseOrocos.cmake file, autolinking is done by parsing manifest.xml file
• ROSbuild managed builds
  • depends on: manifest.xml file, rosbuild cmake macros read it and .pc files, Orocos cmake macros read it to link properly (no build flags from manifest file !)
  • Will only be used if the user explicitly called rosbuild_init() in his top-level CMakeLists.txt
• Catkin managed builds
  • depends on: package.xml file, Orocos generated pkg-config files
  • The Catkin .pc files will be generated but ignored by us (?)
  • No Auto linking
  • We'll also generated .pc files in the devel path during the cmake run

Effects on (Runtime) Environment

• Deployer's import ?
• ROS Deb packages ?
• Orocos Deb packages ?

CMake changes or new macros

• Auto linking
• orocos_use_package()
• orocos_find_package()
• orocos_generate_package()
