Creator uses classes derived from IOutputParser to decide what to list
in the issues tab.

Lot's of them:-) All nicely defined in lots of RegExps.
The actual patterns used do depend a lot on your project though:
Creator uses a list of IOutputParsers and feeds all stdout/stderr text
from the build process through the chain of parsers.
The actual parsers in the chain do depend on OS, build system used,
compiler selected, whether you use Qt or not and probably some more

You will need to add another outputparser to the chain then or extend
an existing parser to match the messages you want.
I am happy to add more patterns, provided they are generally
applicable of course and that somebody provides the necessary test
data (the actual error messages and whether those come from stdout or
I'm using Qt classes, we compile on Linux (GCC), macOS (clang) and Windows (VS
2015/2017). We use C++ and CMake for the build system. The part that throws a
false positive is a custom build step where we call "cmake -P" to load another
generated script. It is that script that puts out the error messages. I used to
have the absolute path to the CMake script file as part of the output but that
seemed to trigger the error. Now I just put "MKDOCS: Something happened" and
that seems to not trigger the error messages.
Could you point me to the regex expressions? I don't really have the source for
QtCreator up and compiling at the moment.
