This file assumes that the compiler doesn't support anything. If building
without CMake, it will be used and if you want to enable things, the file
can be edited.
When using CMake, a proper CompilerCapabilites.h will be generated and
CMake will set the include path order correctly in order to source the
correct file.
It will #define a each of the basic features detected by CMake which can
then be used by other headers (like TypeDef.h) to set things up for
PolyVox.
It is this file which you will have to manually edit and rename if you want
to skip using CMake.
The user can choose static or dynamic libraries using
BUILD_STATIC_LIBRARIES and BUILD_DYNAMIC_LIBRARIES. By default
Windows will only build static libraries and Linux will build both.
