[CMake] Generated source file dependencies

[Julien Michel]

Dear cmake users and developpers,

I have two library, A and B, in two seperated subdirectories A and B.

When building B, the first step is to generate B.h and B.cxx from B.fl 
using FLTK_WRAP_UI.

Now, A depends on B, and it needs B.h to compile properly.

The problem is that when using visual studio, A might be built before B, 
and fails to build because B.h has not yet be generated.

I tried to add a dependency from A to B.h, but I did not succeed in.

Is there any way to ensure B.h will be generated by the time A is 
starting to build ?

Thanks a lot for your answer,

Best regards,

Julien Michel
