# QScintilla is a port to Qt of Neil Hodgson's Scintilla C++ editor control
# available at http://www.riverbankcomputing.com/software/qscintilla/
#
# The module defines the following variables:
#  QSCINTILLA_FOUND - the system has QScintilla
#  QSCINTILLA_INCLUDE_DIR - where to find qsciscintilla.h
#  QSCINTILLA_INCLUDE_DIRS - qscintilla includes
#  QSCINTILLA_LIBRARY - where to find the QScintilla library
#  QSCINTILLA_LIBRARIES - aditional libraries
#  QSCINTILLA_MAJOR_VERSION - major version
#  QSCINTILLA_MINOR_VERSION - minor version
#  QSCINTILLA_PATCH_VERSION - patch version
#  QSCINTILLA_VERSION_STRING - version (ex. 2.6.2)
#  QSCINTILLA_ROOT_DIR - root dir (ex. /usr/local)
