Qt Creator plugin Hunspell can not be used due to missing soname links

The hunspell (qtcreator-spellchecker-plugin) plugin can not be loaded due to missing sonames.

The following Error message is displayed during Qt Creator start up:

Could not resolve dependency 'Core(4.4.1)'
Could not resolve dependency 'TextEditor(4.4.1)'
Could not resolve dependency 'ProjectExplorer(4.4.1)'
Could not resolve dependency 'CppEditor(4.4.1)'
Could not resolve dependency 'CppTools(4.4.1)'

The error seems to be caused by the options that qtcreator is build with and not by the plugin itself.

The "cmake install" command does not install the sonames (symbolic link) without version for the libraries in the "/usr/lib/qtcreator/" folder, because in the function "add_qtc_library" the default value of NAMELINK_OPTION is set to NAMELINK_SKIP.

Therefore, qt-creator plugins on Linux/Unix platforms cannot find the libraries and throws an error during linking.

Change the default from NAMELINK_SKIP to NAMELINK_COMPONENT fix the problem. Before the cmake build system was used, those symbolic links were install.

This suggested patch restore the behavior of qmake.
