allocated dynamic temps from heap instead of stack to get to compile with msvc2010
msvc2010 compilation helps/fixes
maxtime is of type int, so fix comparison to use 0 not 0.0f
Revised CMakeLists.txt (take 2) with changes suggested by Pavel Koshevoy

- Also works on MacOSX
Fixed a linker error (MSVC2010) caused by undefined IMixPlugin destructor.
