hi guys, i am learning tutorial catkinCMakeLists.txt , but i only understand the variable ${PROJECT_NAME}.

there are still lots of variables i do not understand or sure about it, like:

where do

${catkinLIBRARIES} (is that ~/workspace/src/package_name/include ??)

${CATKINDEVELPREFIX}

${CATKINPACKAGEPYTHON_DESTINATION}

${BoostINCLUDEDIRS}

${catkinINCLUDEDIRS}

${${PROJECTNAME}SRCS}) (is that ~/workspace/src/packagename/src ??)

${${PROJECTNAME}EXPORTED_TARGETS}

${CATKINPACKAGELIB_DESTINATION}

${CATKINPACKAGEBIN_DESTINATION}

${CATKINPACKAGEPYTHON_DESTINATION}

${CATKINPACKAGEINCLUDE_DESTINATION}

${CATKINGLOBALINCLUDE_DESTINATION}

${CATKINPACKAGESHARE_DESTINATION}

locate in

and catkinpackage( INCLUDEDIRS include (is that ~/workspace/src/packagename/include ??)

LIBRARIES ${PROJECT_NAME} (??? where it is???)

CATKIN_DEPENDS roscpp (haha i understand this, it's refer to location of ros package, like roscpp is /opt/ros/indigo/share/roscpp)

DEPENDS eigen opencv) (should cmake projects under the path ~/workspace/src, before i use findpackage marco ?)
