Osrm-backend: Please set them or make sure they are set and tested correctly in the CMake files: LUAJIT_LIBRARY (ADVANCED)

I have the same issue like this one: https://github.com/DennisOSRM/Project-OSRM/issues/749

except here it is

-- System supports 64 bits.
-- Configuring OSRM in release mode
-- Looking for LuaJIT...
-- Found LuaJIT: /usr/lib/i386-linux-gnu/libluajit-5.1.so
-- Looking for Luabind...
-- Found Luabind: /usr/lib/libluabind.so
-- Looking for STXXL...
-- Found STXXL: /usr/lib/libstxxl.so
-- Looking for OSMPBF...
-- Found OSMPBF: /usr/lib/libosmpbf.a
CMake Error: The following variables are used in this project, but they are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake files:
LUAJIT_LIBRARY (ADVANCED)
linked by target "osrm-extract" in directory /whatever/Project-OSRM
linked by target "osrm-prepare" in directory /whatever/Project-OSRM

-- Configuring incomplete, errors occurred!

I removed the build directory, created a new one, executed cmake .. again but still the same error message.
