Unfortunately previous commit was only a partial fix, because it broke SQLite support on platforms w/o pkg-config, e.g. Windows. To be honest I just forgot about messy Windows. Now if there is no pkg-config, then user must provide two variables: SQLITE3_INCLUDE_DIRS and SQLITE3_LIBRARIES if (s)he wants to use SQLite backend. These variables are added to cmake-gui for her/his convenience unless they are set by FindPkgConfig module. pkg-config should work also now in Cygwin.
