+By default, it creates a build directory and creates building files in this directory
+The external packages needs to be installed before   
+See doc/BUILD.md for more details 
+The simplest starting point is to:
+install asn1c from source (in doc/BUILD.md: you can also just install asn1c like this ...)
+Then, running ./configure will fail on the packages missing in your Linux, you can install by trial/error
+              
+Possible options are all cmake available options, and OpenAirInterface specific options
+  *** input/output directory
+  --build-dir
+    The building directory (instead of 'current directory'/build)
+  The input file is the current directory file CMakeLists.txt
+
+  *** Binary generation options ***
+  -GNinja or -G\"Unix Makefiles\"
+    cmake method to use Ninja or other build tools (default to standard make)
+  -DCMAKE_C_COMPILER=gcc-4.2 -DCMAKE_CXX_COMPILER=g++-4.2
+    choose compiler
+  -DCMAKE_BUILD_TYPE=Release|RelWithDebInfo|MinSizeRel|Debug
+    predefined cmake options to the compiles (Debug adds -O0 for example)
+  -DAVX512=OFF
+    block AVX512 instructions generation (AVX2 is mandatory in OAI)
+  -DSANITIZE_ADDRESS=True -DSANITIZE_UNDEFINED=True -DSANITIZE_THREAD=True
+    gcc/clang sanitizers 
+
+  *** memory dimensioning
+  -DUE_EXPANSION=True
+    Change the maximum managed UEs in one Cell for 4G and 5G nodeB for 40 to 256
+  -DNB_ANTENNAS_RX=xxx
+    limit the number of managable RX antennas at runtime
+  -DNB_ANTENNAS_TX=xxx
+    limit the number of managable TX antennas at runtime
+
+
+  *** Features generation options ***
+  -DOAI_xxx=ON
+    Enable specific RF boards or simulation
+    xxx can be: USRP BLADERF LMSSDR IRIS SIMU AW2SORI AERIAL ETHERNET FHI72 FHI72_MPLANE
+    WLS (WLS for nfapi instead of regular sockets interface)
+  -DENABLE_xxx=ON
+    enable specific add-on
+    xxx can be
+      TELNETSRV
+      ENBSCOPE UESCOPE NRSCOPE IMSCOPE IMSCOPE_RECORD
+      OAI_IQPLAYER
+      WEBSRV
+      LDPC_CUDA LPDC_AAL LDPC_XDMA
+  -DE2_AGENT=ON
+     Enable the E2 Agent
+
+  *** Tracing options **
+  -DENABLE_LTTNG=ON
+    use lttng as trace output
+  -DT_TRACER=ON
+    Enable T tracer tool instead of regular trace output
+  -DT_TRACER_GUI
+    Adds a GUI to T tracer
+  -DUE_DEBUG_TRACE=ON
+    Adds more traces in UE
+  -DENABLE_VCD_FIFO=ON

+    Enable tracy code profiler instrumentation 
+  
+  *** testing options ***
+  -DENABLE_PHYSIM_TESTS=ON
+     create test scripts to run a set of physical layer auto-tests
+     more details in doc/physical-simulators.md
+     if you run "ctest" after compilation, a set of prepared executions will run
+  -DENABLE_TESTS
+     create unitary test scripts based on ctest googletest
+     more details in docs/UnitTests.md
+     if you run "ctest" after compilation, a set of prepared executions will run
+
+  *** documentation generation
+  -DGENERATE_DOXYGEN=ON
+  generate doxygen documentation
+
+--build-lib <libraries>
