[Cmake] Targets, Output Files, Command Lines

[William A. Hoffman]

I don't think you want this:
LINK_LIBRARIES(bit_streamer)

Also, I would recommend using 
bit_streamer_SOURCE_DIR nad
bit_streamer_BINARY_DIR instead of hard coding the R: path.

Also, the use of $\(InputDir\) $\(InputPath\) in your custom
command will restrict this to only work with visual studio project
files.  The nmake, and unix generation will not work with those.
