Subject: [PATCH] fdpgen: CMake: define NEATOGEN_EXPORTS

fdpgen is part of the neato_layout plugin.

Fixes errors like this using CMake with MinGW:

fdpgen.lib(clusteredges.obj) : error LNK2019: unresolved external symbol __imp_Plegal_arrangement referenced in function compoundEdges [C:\Users\magja\graphviz\build\plugin\neato_layout\gvplugin_neato_layout.vcxproj]
