probably you can at configure stage set the
prefix of include directory as "/usr"

a simple link was also probably enough

   mkdir /include
   ln -s /usr/include/w32api to /include/w32api

but checking the prefix is better.

what is your scope ?
If the original headers are not using that definition
adding it make no difference

By the way
https://docs.microsoft.com/en-us/cpp/porting/modifying-winver-and-win32-winnt?view=msvc-170

reports a different value:

----------------------------------------------------------
#define _WIN32_WINNT_WIN7                   0x0601 // Windows 7
#define _WIN32_WINNT_WIN8                   0x0602 // Windows 8
#define _WIN32_WINNT_WINBLUE                0x0603 // Windows 8.1
#define _WIN32_WINNT_WINTHRESHOLD           0x0A00 // Windows 10
#define _WIN32_WINNT_WIN10                  0x0A00 // Windows 10
