[Qt-creator] [newbie] including ext. lib (libqxt) in qtcreator plugin

[Thomas Ehrnhoefer]

Hi Adam

Thanks for answering. My apologies, the initial post had a line
missing, where I stated that I tried the CONFIG/QXT thing exactly as
you described it.
The result is that that it compiles fine, but once I add this to the code:

    #include "QxtConfirmationMessage"
    [...]
    QxtConfirmationMessage::confirm(widget, tr("Confirm"), text

and nmake and restart QtCreator, I am getting the "module was not
found" dialog at startup.

What puzzles me is that during building, the parameters list (as an
example) both
     -I"c:\work\Qt\qt-everywhere-opensoure-opensource-src-4.7.2\include\QxtCore"
 and
    -I"c:\Qxt\include\QxtCore"

But that might just be normal. The qt-src folder does not contain any
qxt stuff (except a QxtDesignerPlugins.dll, qxtvars.prf and qxt.prf),
the rest is all just in c:/qxt/....

I guess I can assume that if my plug in compiles and runs correct
without libqxt it is setup correct, and the problems are somehow in
how I try to use/include libqxt.

P.S.: I sent the original message to libqxt-users at libqxt.org after
signing up (and confirming), but maybe a first message is in review?
No clue why it's not showing.
