The easiest way is to put the headers and libs where your compiler will 
look for them. Such as:
D:\path\to\compiler\include\ogg\ogg.h
D:\path\to\compiler\include\vorbis\vorbis.h
D:\path\to\compiler\include\vorbis\vorbisfile.h
D:\path\to\compiler\include\FLAC\all.h
..etc..

and

D:\path\to\compiler\lib\FLAC.lib
D:\path\to\compiler\lib\vorbisfile.lib
D:\path\to\compiler\lib\vorbis.lib
D:\path\to\compiler\lib\ogg.lib

The other option is to manually specify the include paths and libs using 
CMakeSetup.exe. After you first configure Alure, it should have Cache 
Values for OGG_LIBRARY, OGG_INCLUDE_DIR, etc, which you can fill in 
manually.

Unfortunately I don't know how easy it will be to use the static 
versions of these libs, due to the way Windows dresses imported 
functions from DLLs. It's technically feasible, but it may need some 
source changes depending on how the Ogg/FLAC headers are told to not use 
dllimport.

These will be things I intend on fixing/improving for the next release 
(which is likely a ways off still, unfortunately).

Try using forward slashes:
"d:/flac-1.2.1/flac-1.2.1/obj/release/lib"
CMake probably wants \\ for a single backslash, but it should recognize 
a forward slash as a directory separator regardless.

It still works with the normal libs. Using Tremor is just an option for 
systems that don't have good floating-point performance.
