The correct way is this (in this case we are using pkgconfig information): if( WITH_XEXT ) pkg_search_module( XEXT xext ) if( NOT XEXT_FOUND ) tde_message_fatal( "You requested Xext support, but is was not found on your system (or devel package is not installed' ) endif( ) check_include_file( "X11/extensions/shape.h" HAVE_X11_EXTENSIONS_SHAPE_H ) endif( ) tde_add_executable( ksnapshot AUTOMOC SOURCES ksnapshotiface.skel main.cpp ksnapshot.cpp regiongrabber.cpp windowgrabber.cpp ksnapshotwidget.ui LINK kdeprint-shared ${XEXT_LIBRARIES} DESTINATION ${BIN_INSTALL_DIR} ) -- Serghei
