Well, first it looks for qt.h like this:

FIND_PATH(QT_INCLUDE_DIR qt.h
 
"[HKEY_CURRENT_USER\\Software\\Trolltech\\Qt3Versions\\3.2.1;InstallDir]/include/Qt"
 
"[HKEY_CURRENT_USER\\Software\\Trolltech\\Qt3Versions\\3.2.0;InstallDir]/include/Qt"
 
"[HKEY_CURRENT_USER\\Software\\Trolltech\\Qt3Versions\\3.1.0;InstallDir]/include/Qt"
   $ENV{QTDIR}/include
   ${GLOB_PATHS_BIN}
   /usr/local/qt/include
   /usr/lib/qt/include
   /usr/lib/qt3/include
   /usr/include/qt
   /usr/share/qt3/include
   C:/Progra~1/qt/include
   /usr/include/qt3
   )

Then, it makes sure that the path is valid by checking for qglobal.h:

# if qglobal.h is not in the qt_include_dir then set
# QT_INCLUDE_DIR to NOTFOUND
IF(NOT EXISTS ${QT_INCLUDE_DIR}/qglobal.h)
   SET(QT_INCLUDE_DIR QT_INCLUDE_DIR-NOTFOUND CACHE PATH "path to Qt3 
include directory" FORCE)
ENDIF(NOT EXISTS ${QT_INCLUDE_DIR}/qglobal.h)


Either of those could have failed...
