############################## HOW TO ##################################
# Suppose the library name is XX
# Usually what you need to change are: staticlink, LIB_VERSION, NAME and DLLDESTDIR.
# And rename xx-buildlib and LIBXX_PRI_INCLUDED
# the contents of libXX.pro is:
#    TEMPLATE = lib
#    QT -= gui
#    CONFIG *= xx-buildlib
#    STATICLINK = 1 #optional. default is 0, i.e. dynamically link
#    PROJECTROOT = $$PWD/..
#    include(libXX.pri)
#    preparePaths($$OUT_PWD/../out)
#    HEADERS = ...
#    SOURCES = ...
#    ...
# the content of other pro using this library is:
#    TEMPLATE = app
#    PROJECTROOT = $$PWD/..
#    STATICLINK = 1 #or 0
#    include(dir_of_XX/libXX.pri)
#    preparePaths($$OUT_PWD/../out)
#    HEADERS = ...
#    SOURCES = ...
