[CMake] FLTK_IMAGES_LIBRARY Link problem

[Luca Rinaudo]

Dear,
I'm quite new to CMake and I would like to build an application with itk, vtk 
and fltk. I managed to build a simple program that link the three parts 
together, but I still have some problem linking in the right way the fltk 
libraries.
Infact, when I try to use these lines to create a background in a window

fl_register_images(); 
Fl_Box *background = 
Fl_JPEG_Image *background_img = 
background->image(background_img);
 
I have these errors
 2>fltkimagesd.lib(Fl_JPEG_Image.obj) : error LNK2019: riferimento al simbolo 
esterno _jpeg_read_scanlines non risolto nella funzione "public: __thiscall 
Fl_JPEG_Image::Fl_JPEG_Image(char const *)" (??0Fl_JPEG_Image@@QAE at PBD@Z)
.....
 
2>fltkimagesd.lib(Fl_PNG_Image.obj) : error LNK2019: riferimento al simbolo 
esterno _png_read_end non risolto nella funzione "public: __thiscall 
Fl_PNG_Image::Fl_PNG_Image(char const *)" (??0Fl_PNG_Image@@QAE at PBD@Z)
.....
 
I think that my problem could be related to the CMake list enclosed, but I 
cannot figure out what's wrong!!
 
Does anyone can help me?
 
Thank you in advance,
 
Best regards,
 
Luca
