Hi: I've define: EXPAT_INCLUDE to: c:\program files\expat\source\lib and EXPAT_BIN to c:\program files\expat\bin I've also added these paths to visual studio. I get the following error: libs\graph\src\graphml.cpp(13) : fatal error C1083: Cannot open include file: 'expat.h': No such file or directory Any help appreciated.
