Use Eclipse CDT settings in Qt project file (to exclude double configuration work)

This issue appears because of double configuration of qt project in eclipse, i.e. for highlighting and codecompletion I must configure eclipse project and for building I configure qt's pro-file. Plugin has some abilities of integration those are buggy (double inclusion of the same file and etc).

Some eclipse cdt settings can be used by plugin:

• project files
• compiler search paths
• linker search paths
• link libraries
• compiler options
• linker options
• so on

If file is excluded from build in cdt it can't appear in pro-file.
pro-file must be an intermediate file, that is generated before build, and eclipse project file must be primary.
Plugin can generate pro-file from eclipse cdt project then generate makefile. After this eclipse can build application.

For more flexibility plugin can contain custom section - text field that is represents a part of generated pro-file
