Brooks's stock continues to rise after he was named in Chris Coleman's Wales squad for the very first time on Thursday, having been crowned man of the match in Sunday's Steel City derby win against Sheffield Wednesday - which was only his second league start for the second-place Blades.
Everton have already been credited with interest in the Warrington-born 20-year-old, dating back to the start of the summer.
But United boss Wilder is adamant Brooks will not be following his former Bramall Lane colleague Dominic Calvert-Lewin to Merseyside.
"He won’t be going anywhere, I’ve said that," the 50-year-old told BBC Radio Sheffield. "I’m building here and he’s a big part of that.
"We want to keep hold of all our players, especially the ones that are doing well. Sometimes there are casualties, some players that aren’t playing that want to go and play football. I totally understand and respect that but we’re building here and Brooko is going nowhere."
Calvert-Lewin isn't the only former Sheffield United employee on Everton's books, with Phil Jagielka captain of the Toffees, and David Unsworth and Jamie Hoyland both heavily involved in the club's Under-23 set up, as manager and head of recruitment respectively.
Speaking to Sheffield Live TV in June Hoyland admitted to being aware of Brooks' talent: "He’s a lad who got released off Man City when he was 16, so obviously his pedigree is good. I think he’s 19 - he still looks, probably, about 14/15. And that’s the thing about him, he’s still not developed physically [into] what he should be.
"I’ve seen Sheffield United’s Under-23s quite a lot. He’s a good player. He drifts, he can get on the ball, he’s got great balance, he goes past people and he can pick a pass."
Will Sheffield United keep hold of Brooks?
