# Qt Widgets for Technical Applications
|

# available at http://www.http://qwt.sourceforge.net/
|
||||
#
|
||||
# The module defines the following variables:
|
||||
# Qwt_FOUND - the system has Qwt
|
||||
# QWT_INCLUDE_DIR - where to find qwt_plot.h
|
||||
# QWT_INCLUDE_DIRS - qwt includes
|
||||
# QWT_LIBRARY - where to find the Qwt library
|
||||
# QWT_LIBRARIES - aditional libraries
|
||||
# QWT_MAJOR_VERSION - major version
|
||||
# QWT_MINOR_VERSION - minor version
|
||||
# QWT_PATCH_VERSION - patch version
|
||||
# QWT_VERSION_STRING - version (ex. 5.2.1)
|
||||
# QWT_ROOT_DIR - root dir (ex. /usr/local)
|
||||
#
|
||||
# It also defines this imported target:
|
||||
# Qwt::Qwt
