+COMPILER_PREFIX=<string>
+ If you build with multiple versions of the same compiler, you can put
+ their outputs into directories like "vc6_lib", "vc8_lib" etc. instead of
+ "vc_lib" by setting this variable to e.g. "vc6". This is merely a
+ convenience variable, you can achieve the same effect (but different dir
+ names) with the CFG option.
