#Useful Preprocessor Directives:
# -DUSE_DOUBLE = use double instead of float for most operations.
# -DNOZLIB = use puff.c
# -DTCC = various things needed for TCC.
# -DWINDOWS -DWIN32 = Building for Windows
# -DHIDAPI = Build vive driver to use USBHID instead of interrupt/control messages.
# -DRUNTIME_SYMNUM = Don't assume __attribute__((constructor)) works.  Instead comb for anything starting with REGISTER.
