lyx_mirror/config/qt4.m4
Jean-Marc Lasgouttes fa2a87de9b Qt4 autoconf cleanup.
* config/qt4.m4 
	(QT4_FIND_PATH, QT_FIND_UIC4, QT_FIND_MOC4): remove,
	AC_PATH_PROGS does this very well. 
	(QT4_DO_PKG_CONFIG): add $QT4DIR/lib to pkg-config search path;
	do not run QT4_DO_MANUAL_CONFIG on failure. 
	(QT4_DO_MANUAL_CONFIG): remove some code.
	(QT4_DO_IT_ALL): move code to handle --with-foo here; move
	code to search for moc/uic here; call QT4_DO_PKG_CONFIG first,
	and QT4_DO_MANUAL_CONFIG on failure.
