Missing header (gcc 15)

[José Matos]

With that fix the compilation fails in the linking stage:

/usr/bin/ld: liblyxcore.a(Buffer.o):(.rodata+0x190): multiple
definition of `QtPrivate::IsFloatType_v<_Float16>';
Compare.o:(.rodata+0x278): first defined here
/usr/bin/ld: liblyxcore.a(Language.o):(.rodata+0x64): multiple
definition of `QtPrivate::IsFloatType_v<_Float16>';
Compare.o:(.rodata+0x278): first defined here
/usr/bin/ld: liblyxcore.a(Server.o):(.rodata+0x58): multiple definition
of `QtPrivate::IsFloatType_v<_Float16>'; Compare.o:(.rodata+0x278):
first defined here
/usr/bin/ld: liblyxcore.a(lyxfind.o):(.rodata+0x4c): multiple
definition of `QtPrivate::IsFloatType_v<_Float16>';
Compare.o:(.rodata+0x278): first defined here

This fails in other cases but the is always
`QtPrivate::IsFloatType_v<_Float16>'

I guess that I will wait. :-)
