hallo..<br>I'm trying to install vtkFLTK, according to the instructions I found in:http://vtkfltk.sourceforge.net/Building.html<br><br>When I run cmake it complains that it cannot find FLTK.. namely:<br>CMake Error: FLTK not found. Please set the FLTK_INCLUDE_DIR cmake cache entry. This is either the root of the build tree, or PREFIX/include for an installation.<br><br>What should I do???????<br><br>Thanks a lot<br>Ale<br><p>
