I wasn't aware of the importance of the order in which the libraries are
passed to the linker, so in the dependency list in src/CMakeLists.txt
I naively started with the most basic libraries first. This is WRONG.
The linker searches and resolves symbols in the order that they appear.
If library A contains a call to a function from library B, we have to
put A before B, otherwise the linker won't know that something in B
needs to be resolved.

In order to be able to use the installed versions of the library's headers
(and the libraries itself) the directories structure of the source has to
be reprodused in the install location.
This modification is needed by the NumPy interface of KernelShark.

The Doxygen documentation, including its configuration file, have been
moved to another directory. Therefore the paths, used by Doxygen to find
its input, have to be changed accordingly.

My original intend was to fix a Doxygen warning complaining about a data
member of a class not being documented. However, when I tried to write
explanation for this data member (KsCaptureMonitor::_captureStatus),
I realized that it is completely useless and that it actually violates
the encapsulation principle, since it holds the return status of the
capture process, but the capture process itself is owned by another
class (KsCaptureDialog).

This one is wrong. Please ignore it.
I am sending v2.
