The External Dependencies folder is populated by IntelliSense   the contents of the folder do not affect the build at all  you can in fact disable the folder in the UI    You need to actually include the header  using a  include directive  to use it   Depending on what that header is  you may also need to add its containing folder to the  Additional Include Directories  property and you may need to add additional libraries and library folders to the linker options  you can set all of these in the project properties  right click the project  select Properties    You should compare the properties with those of the project that does build to determine what you need to add
