# ==================================================================================
# Caneda project
#
# FindQwt.cmake file to use in cmake to find Qwt libraries. Can be replaced once
# cmake upstream implements its own FindQwt.cmake
#
# The module defines the following variables:
# QWT_FOUND - Qwt was found
# QWT_INCLUDE_DIR - Qwt include directories (qwt.h)
# QWT_LIBRARY - Qwt library directory
# QWT_MAJOR_VERSION - major version
# QWT_MINOR_VERSION - minor version
# QWT_PATCH_VERSION - patch version
# QWT_VERSION_STRING - version (ex. 5.2.1)
