Creator can be pickier about .pro syntax than qmake, which can lead to the syntax highlighter not using the right include path, so not finding include files (which in turn, can lead to it flagging syntax errors due to it not having included the include file). So double check that your .pro syntax is valid. 

There’s also an environment variable you can set that’ll supposedly make Creator give more verbose warnings as it parses things - QTCREATOR_DUMP_FILENAME_WHILE_PARSING. Once that’s set, run Creator in a way that you can see it’s console output and look for the “Parsing file” lines, to check that it’s finding the include files as you expect - a bad INCLUDEPATH, combined with #include “foo/bar” seems to be one problem people have seen.
