Khem Raj d19ffe7459 sysdig: pin Curses to target sysroot so chisel uses LuaJIT lua.h
chisel does #include "lua.h" and links libluajit-5.1.so, but the link
failed with undefined Lua symbols (luaL_openselectedlibs, lua_setglobal,
lua_getglobal, lua_pcallk). Those come from the stock Lua >= 5.4 header,
not LuaJIT.

The stray stock lua.h reaches the target compile line via ncurses.cmake:
find_package(Curses) resolves CURSES_INCLUDE_DIR to the native sysroot
(recipe-sysroot-native/usr/include, which also carries ncurses.h/form.h
and, dragged in by lua-native, lua.h), then include_directories() places
that dir ahead of the LuaJIT include dir. The prior CXXFLAGS -I workaround
could not win because CMake orders target include_directories before
CMAKE_CXX_FLAGS.

Pin CURSES_INCLUDE_DIR/CURSES_LIBRARIES to the target sysroot so the native
include dir never leaks into the target build; lua.h then resolves through
LUAJIT_INCLUDE and matches the linked library.

# sysdig's chisel code does #include "lua.h", but the only lua.h it must ever
# resolve to is LuaJIT's (it links libluajit-5.1.so). The native sysroot also
# ships a stock Lua header (lua-native pulls lua.h into
# recipe-sysroot-native/usr/include), and in Lua >= 5.4.4 luaL_openlibs is a
# macro for luaL_openselectedlibs while lua_setglobal/getglobal/pcallk are real
# symbols, none of which LuaJIT provides -- so compiling chisel against it makes
# the link fail with undefined Lua symbols.
#
# That native include dir leaks onto the target compile line because sysdig's
# ncurses.cmake runs find_package(Curses), which resolves CURSES_INCLUDE_DIR to
# the native sysroot (native also carries ncurses.h/form.h) and then does
# include_directories(${CURSES_INCLUDE_DIR}), placing it ahead of the LuaJIT
# include dir. Pin Curses to the target sysroot so the native dir (and its stray
# lua.h) never reaches the target build; lua.h then resolves via LUAJIT_INCLUDE.
#Add include dir to find driver_config.h
