Build instructions:

1. install cmake
2. mkdir build
3. cd build
4. cmake ..
5. make install

cmake Options:
  -DBUILD_SHARED_LIBS
    By default SHARED libraries are created and applications are linked to it.
    Use -DBUILD_SHARED_LIBS=OFF while invoking cmake to create STATIC libraries
    and link applications to it.

    Ex. cmake -DBUILD_SHARED_LIBS=OFF ..

  -DCMAKE_INSTALL_PREFIX
    Default is to install to /usr/local, use -DCMAKE_INSTALL_PREFIX=
    when invoking cmake to specify another install location.

You may need to update the libbpf git submodule:

git submodule update --init --recursive
