falco/CMakeLists.txt
Mark Stemm 345452836b Changes related to use of kernel module. 
While building falco from source, I found a couple of problems related
to use of kernel modules:

1. The falco build needs driver_config.h from the sysdig repo, but it
isn't created by default.

[ 50%] Building C object userspace/libscap/CMakeFiles/scap.dir/scap.c.o
/mnt/sf_stemm/work/src/sysdig/userspace/libscap/scap.c:34:40: fatal error: ../../driver/driver_config.h: No such file or directory
compilation terminated.c

Fixed by adding ${SYSDIG_DIR}/driver to CMakeLists.txt. I did notice
that after doing this the object files were in the sysdig/driver
directory, but I don't think this is related to the Makefiles/CMakeFiles
in the sysdig/driver directory?

2. Falco needs the sysdig kernel module, but it may not be loaded if no
other sysdig is installed.

Added notes to the README that discuss loading the kernel module by hand
if no binary sysdig is installed.
