# Find the Qwt 5.x includes and library, either the version linked to Qt3 or the version linked to Qt4

# On Windows it makes these assumptions:
|
|
# - the Qwt DLL is where the other DLLs for Qt are (QT_DIR\bin) or in the path
|
|
# - the Qwt .h files are in QT_DIR\include\Qwt or in the path
|
|
# - the Qwt .lib is where the other LIBs for Qt are (QT_DIR\lib) or in the path
|
|
#
|
|
# Qwt5_INCLUDE_DIR - where to find qwt.h if Qwt
|
|
# Qwt5-Qt4_LIBRARY - The Qwt5 library linked against Qt4 (if it exists)
|
|
# Qwt5-Qt3_LIBRARY - The Qwt5 library linked against Qt4 (if it exists)
|
|
# Qwt5-Qt4_FOUND - Qwt5 was found and uses Qt4
|
|
# Qwt5-Qt3_FOUND - Qwt5 was found and uses Qt3
|
|
# Qwt5_FOUND - Set to TRUE if Qwt5 was found (linked either to Qt3 or Qt4)
