Now you can set OPTION_BUILD_SHARED_LIBS:BOOL=ON to build FLTK dll's with Visual Studio. Tested and works (Visual Studio 2010 + 2015). Note: Linux fixes included, tested and works (Ubuntu). Todo: dll names and target directories may need some changes. We really need to get rid of that "_SHARED" suffix in .so names. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.3-porting@11867 ea41ed52-d2ee-0310-a9c1-e6b18d33e121
