CMake 3.8.0 Qt automoc support

Fixes #112, #114.

Fix option type in add_sanitizers check

Show fewer warnings for targets.

Instead of printing the same message over and over again, if a target can't use
a specific sanitizer, the message will be printed only once for the first
affected target now.

Restructuring and new features

In some special cases static linking the sanitizers won't work, and you have to
preload libasan. To find the right libasan depending on the application to be
executed, a wrapper script was added. The location of the wrapper script can be
accessed via ASan_WRAPPER variable.
