csysdig fails to link when stock Lua is also present in the sysroot:
ld.lld: error: undefined symbol: luaL_openselectedlibs
>>> referenced by chisel.cpp:1190
ld.lld: error: undefined symbol: lua_pcallk
ld.lld: error: undefined symbol: lua_setglobal
sysdig's chisel code does #include "lua.h" and links against LuaJIT
(lua${JIT}), but the recipe-sysroot also carries stock Lua headers
(openembedded-core lua installs lua.h into ${includedir}). Those headers
win the include search over ${includedir}/luajit-2.1, so the chisel
objects are compiled against stock Lua while the binary links
libluajit-5.1.so. In Lua >= 5.4.4 luaL_openlibs is a macro for
luaL_openselectedlibs and lua_setglobal/lua_pcallk are real symbols,
none of which LuaJIT (a Lua 5.1 ABI) provides, hence the undefined
references. -DLUA_INCLUDE_DIR does not help: sysdig's luajit.cmake only
consults it in its stock-Lua fallback, not when it finds LuaJIT.
Prepend ${STAGING_INCDIR}/luajit-2.1 to CFLAGS/CXXFLAGS. These land in
CMAKE_CXX_FLAGS, which precede CMake's generated -I includes, so LuaJIT's
lua.h is found first and matches the linked library.
