[Insight-users] CMAKE command to link Fltk (fluid) in a code

[Luis Ibanez]

Hi Alexandre,

Thanks for pointing this out.

You are right, the command

    ADD_GUI_EXECUTABLE

is actually a macro defined in the top
CMakeLists.txt file of InsightApplications.

It contains extra code for making an executable
work in a Mac (e.g. manage resources...).

If you are not using a Mac, you can simply set

     ADD_EXECUTABLE


The

     TK_DISABLE_FLTK_GENERATED_WARNINGS

is only intended to suppress a lot of signed/unsigned
warnings generated from FLTK headers. That can also
be removed.


----

About the single file issue...

If you really want to do this manually, what
you want to use is the ADD_CUSTOM_COMMAND().

Define a ADD_CUSTOM_COMMAND() for invoking FLUID
and generating the .cxx file. Then you set the
.cxx file as the only source file in you
ADD_EXECUTABLE command.



For details on this command just type


     cmake --help ADD_CUSTOM_COMMAND




CMake has a built-in help for all the commands.



   Regards,


      Luis
