In WConfig.h the current Wt version is made up from 3 version numbers:

#define WT_SERIES 2
#define WT_MAJOR  99
#define WT_MINOR  0

/*! \brief A constant that encodes the library version of %Wt
 *
 * You may use this constant to check for the version of %Wt at build-time.
 */
#define WT_VERSION (((WT_SERIES & 0xff) << 24) | ((WT_MAJOR & 0xff) <<
16) | ((WT_MINOR & 0xff) << 8))

However, when you test for Wt 2.99.0 or greater you need something
like this in your code:

#if WT_VERSION >= 0x02630000
...

Because 99 is hex 0x63. Instead, shouldn't the 3 numbers be in hex:

#define WT_SERIES 0x2
#define WT_MAJOR  0x99
#define WT_MINOR  0x0

So that the code check can be:

#if WT_VERSION >= 0x02990000
...

Which is more readable.
