[Cmake] Generating code during the build: Fluid FLTK

[Franck Bettinger]

Hi Luis,

It appears that the .h file can not be found. As this file does not exist at 
the time of the target creation, I've added a rule in cmMakeDepend.cxx that 
also look if the file will not be generated. Unfortunately there was a 
problem with the matching of the path (since we only know the name of the 
file itself and not its path). I had to guess the path by looking at the 
include directories.

So you have to add an INCLUDE_DIRECTORIES rule in your CMakeLists.txt that 
tells cmake where to look for.

For instance, with the Qt ui wrapper and vxl, I use a rule like this :

INCLUDE_DIRECTORIES( ${allvxl_BINARY_DIR} )
...
    QT_WRAP_UI(drawing
      drawing_ui_headers
      drawing_ui_sources
      drawing_interfaces
    )

and I include the .h file using :
#include <programs/drawing/drawing.h>

so that cmMakeDepend.cxx can find that the file 
${allvxl_BINARY_DIR}/programs/drawing/drawing.h
is in the target list.

Beware not to use a "/" at the end of your INCLUDE_DIRECTORIES path because 
the algorithm append it automatically and two "/" would cause the matching to 
fail.

I hope it helps.

Franck
