Hi.

Are the dsound headers and import libs present on the system? Where are 
dsound.h and dsound.lib for you? If worse comes to worse, you can use 
cmake-gui or whatever to manually set the DSOUND_INCLUDE_DIR and 
DSOUND_LIBRARY variables to the appropriate values (the path where 
dsound.h is, and the full path+filename for dsound.lib, respectively).

Alternatively, you should be able to use the prebuilt binaries:
http://openal-soft.org/openal-binaries/openal-soft-1.17.2-bin.zip
which has OpenAL Soft's headers, import libs, and DLLs already made and 
with proper support for the various Windows audio backends.
