26 # Simply invoke AT_WITH_QT in your configure.ac. AT_WITH_QT can take
27 # arguments which are documented in depth below. The default arguments are
28 # equivalent to the default .pro file generated by qmake.
30 # Invoking AT_WITH_QT will do the following:
31 # - Add a --with-qt option to your configure
32 # - Find qmake, moc and uic and save them in the make variables $(QMAKE),
34 # - Save the path to Qt in $(QT_PATH)
35 # - Find the flags to use Qt, that is:
36 # * $(QT_DEFINES): -D's defined by qmake.
37 # * $(QT_CFLAGS): CFLAGS as defined by qmake (C?!)
38 # * $(QT_CXXFLAGS): CXXFLAGS as defined by qmake.
39 # * $(QT_INCPATH): -I's defined by qmake.
40 # * $(QT_CPPFLAGS): Same as $(QT_DEFINES) + $(QT_INCPATH)
41 # * $(QT_LFLAGS): LFLAGS defined by qmake.
42 # * $(QT_LDFLAGS): Same thing as $(QT_LFLAGS).
43 # * $(QT_LIBS): LIBS defined by qmake.
45 # You *MUST* invoke $(MOC) and/or $(UIC) where necessary. AutoTroll provides
46 # you with Makerules to ease this, here is a sample Makefile.am to use with
47 # AutoTroll which builds the code given in the chapter 7 of the Qt Tutorial:

74 # ------------------------------------------------
75 # Enable Qt support and add an option --with-qt to the configure script.
77 # The QT_modules argument is optional and defines extra modules to enable or
78 # disable (it's equivalent to the QT variable in .pro files). Modules can be
79 # specified as follows:
81 # AT_WITH_QT => No argument -> No QT value.
82 # Qmake sets it to "core gui" by default.
83 # AT_WITH_QT([xml]) => QT += xml
84 # AT_WITH_QT([+xml]) => QT += xml
85 # AT_WITH_QT([-gui]) => QT -= gui
86 # AT_WITH_QT([xml -gui +sql svg]) => QT += xml sql svg
89 # The QT_config argument is also optional and follows the same convention as
90 # QT_modules. Instead of changing the QT variable, it changes the CONFIG
91 # variable, which is used to tweak configuration and compiler options.
93 # The last argument, QT_misc (also optional) will be copied as-is the .pro
94 # file used to guess how to compile Qt apps. You may use it to further tweak
95 # the build process of Qt apps if tweaking the QT or CONFIG variables isn't
