Rolf Eike Beer 8ebf74b02f Find* (and some other): use ${CMAKE_CURRENT_LIST_DIR} in include()
This solves a lots of warnings, e.g. in the FindModulesExecuteAll test. If the
installed version on the system is rather old this may even lead to bugs, e.g.

# CURSES_FOUND - system has Curses
# CURSES_INCLUDE_DIR - the Curses include directory
# CURSES_LIBRARIES - The libraries needed to use Curses
# CURSES_HAVE_CURSES_H - true if curses.h is available

# Set CURSES_NEED_NCURSES to TRUE before the find_package() command if NCurses
