* rework of the build structure, adopt to standard cmake package structure7.4

* check versions when loading the libs
* introduction of the AudioManagerCore
* give control plugin as file or directory
* remove SQLITE
* either find and use gmock or build and install it
* fixed [Bug 411]
* compile flag gnu11 is now used
