OK, so I modified that part as follows:

         { // Pkg Config support
             qDebug() << "pkgConfig support";
             QStringList pkgConfig = pro->variableValue(PkgConfigVar);
             if (!pkgConfig.isEmpty()) {
                 qDebug() << "running pkgConfig support";
                 pkgConfig.prepend("--cflags-only-I");
                 qDebug() << "pkgConfig: ";
                 qDebug() << pkgConfig;
                 QProcess process;
                 process.start("pkg-config", pkgConfig);
                 process.waitForFinished();
                 QString result = process.readAllStandardOutput();
                 qDebug() << "pkgConfig RESULTS:";
                 qDebug() << result;
                 foreach(const QString &part, result.trimmed().split(' 
', QString::SkipEmptyParts)) {
                     info.includes.append(part.mid(2)); // Chop off "-I"
                     qDebug() << "appending: " << part.mid(2);
                 }
             }
         }

and when I run qt-creator (with PKG_CONFIG_PATH variable set to 
/home/bettini/usr/local/lib/pkgconfig), I get this output in the console 
which looks good:

pkgConfig support
running pkgConfig support
pkgConfig:
("--cflags-only-I", "source-highlight-qt4")
pkgConfig RESULTS:
"-I/home/bettini/usr/local/include -I/usr/share/qt4/mkspecs/linux-g++ 
-I. -I/usr/include/qt4/QtCore -I/usr/include/qt4/QtGui 
-I/usr/include/qt4 -I/home/bettini/usr/local/lib/include
"
appending:  "/home/bettini/usr/local/include"
appending:  "/usr/share/qt4/mkspecs/linux-g++"
appending:  "."
appending:  "/usr/include/qt4/QtCore"
appending:  "/usr/include/qt4/QtGui"
appending:  "/usr/include/qt4"
appending:  "/home/bettini/usr/local/lib/include"

and the directory /home/bettini/usr/local/lib/include contains the 
header directories:

srchilite
srchiliteqt

still, in my project in qt-creator these includes:

#include <srchilite/versions.h>
#include <srchilite/sourcehighlight.h>
#include <srchilite/parserexception.h>
#include <srchilite/lineranges.h>

#include <srchiliteqt/ColorDialog.h>
#include <srchiliteqt/Qt4SourceHighlightStyleGenerator.h>

are not recognized (they are underlined in yellow)

hope this helps
thanks
	Lorenzo
