Do you know <http://autoconf-archive.cryp.to/bnv_have_qt.html>? We're using an older version of this macro in some code, with something like this (you also need pkg.m4 for it): PKG_CHECK_MODULES(QT, [qt-mt >= 3.1], [CPPFLAGS="$CPPFLAGS $QT_CFLAGS" LIBS="$QT_LIBS $LIBS" AC_PATH_PROG([MOC], [moc], [:])], [BNV_HAVE_QT CPPFLAGS="$CPPFLAGS $QT_CXXFLAGS" LIBS="$QT_LIBS $LIBS" MOC="$QT_MOC"]) (improvements and bug reports welcome). > - The previous use was mostly been thought to be performed at configure > time, but it maybe be interesting to perform this at autoreconf time.

This is what we do in Makefile.am: bin_PROGRAMS = foo foo_SOURCES = bar.cpp bar.h baz.cpp baz.h ... nodist_foo_SOURCES = $(MOC_SRC) ... BUILT_SOURCES = $(MOC_SRC) ... CLEANFILES = $(MOC_SRC) ... SUFFIXES = .cpp .moc .h MOC_SRC = bar.moc baz.moc ... If you want to distribute .moc files, you can probably just move them from nodist_foo_SOURCES to foo_SOURCES. And from CLEANFILES to MAINTAINERCLEANFILES. If the list of .moc files matches the list of header files, you can further factor and simplify to: foo_hdrs = bar.h baz.h foo_SOURCES = $(foo_hdrs) bar.cpp baz.cpp ... MOC_SRC = $(foo_hdrs:.h=.moc) We don't use uic, though. FWIW, yes, I know the SUFFIXES list is not crucially necessary. It is not wrong though, either, and I think it helps being clear.
