[Insight-users] Re: Help learning ITK : Order matters in command lines of a CMakeLists.txt file

[Luis Ibanez]

Hi Hong,

CMake is now being made more procedural, so the order in which
you put the CMake commands in a CMakeLists.txt file matters more
now.

What the error message is telling you is that you have the order

    TARGET_LINK_LIBRARIES( FooTarget  FooLibrary )
    ADD_LIBRARY( FooLibrary )

So.. in the first line you are adding a dependency to the FooLibrary
that doesn't exist yet.  CMake is asking you to swap the order of the
lines to be


    ADD_LIBRARY( FooLibrary )
    TARGET_LINK_LIBRARIES( FooTarget  FooLibrary )



As you migrate to CMake 2.2 you will see more and more of these
ordering issues.



    Regards,


      Luis
