QtAutogen: Only add source files to the target if AUTORCC is ON.

The qtx_add_resources() macro adds the resource file to the output list
to maintain file-level dependencies.  Having the qrc file in a target
sources is a precondition for AUTORCC to function.

When processing the source files of a target, only add the generated
qrc_<file>.cpp to the target sources if AUTORCC is ON.  This avoids
pre-porting conflict with the macro.

In commit v2.8.5~176^2~2 (FindOpenSSL: We should only use hints to find
OpenSSL, 2011-03-28) values for HINTS and PATHS of find_* calls were
computed everywhere but only used on Windows.  Use them everywhere.
