[PATCH v4 1/9] kernel-shark-qt: Add Cmake build system for the Qt based KernelShark

["Yordan Karadzhov (VMware)" <y.karadz@gmail.com>]

This patch adds in /kernel-shark-qt a simple CMake building
infrastructure, to be used by the new, Qt-based version of
KernelShark. Currently, this does not build any objects.
It only generates a header file (src/KsDeff.h) containing some
user-specific definitions. The building infrastructure
is necessary for the coming changes.
