The moment of truth has arrived for Carmelo Anthony.

Tuesday night, Anthony will be in a place he cherishes. Not Houston, but Baltimore, where he will host The Basketball Tournament — a month-long event that is down to its final four.

Keeping a low profile lately, Anthony will be front and center Tuesday at Coppin State, watching a Syracuse alumni team face Overseas Elite in one semifinal.

In the other, Ohio State alumni, which features Nets target Jared Sullinger, play Team Challenge ALS, a Boston College squad fighting to raise money to support alumnus Pete Frates who is suffering from Lou Gehrig’s disease.

The Knicks’ 33-year-old recent recluse has yet to give an interview since the regular-season finale April 12, when he saw “the writing on the wall.’’ The indication was he knew the club wanted to rebuild without him.

In the next few days, Anthony will have a chance to speak his piece.

Phil Jackson is out as president, but the franchise’s strategy hasn’t changed much. A stalemate has ensued as sources indicate Anthony only wishes to waive his no-trade clause to go to the Rockets. Not even Cleveland, which is in turmoil, is good enough for Anthony as the Cavaliers are dealing with Kyrie Irving’s trade demand.

The Knicks’ management tandem of Steve Mills-Scott Perry claim it won’t trade Anthony to Houston unless it cobbles together a solid deal that makes sense for the Knicks’ future. Nothing has materialized.

In fact, a source told The Post the signing of veteran point guard Ramon Sessions partly was due to him connecting better with Anthony and Kristaps Porzingis than did Derrick Rose, who left for Cleveland via free agency.

Anthony has also dealt with the very public separation from his wife, La La.

All those issues swirl about as Anthony hosts The Basketball Tournament that concludes Thursday. Anthony also will attend a charity event Wednesday with Catherine Pugh, the mayor of Baltimore.

The $2 million winner-take-all competition featuring former NBA and Division I players is in its fourth year. Anthony, ironically, engineered its move from New York to Baltimore for the semifinals and finals, which will be televised by ESPN. Anthony lived in Brooklyn until age 10 before moving to Baltimore.

“After years of watching TBT, I decided to get involved,’’ Anthony stated in a release. “It’s a tournament for people to live out their basketball dreams and that’s exciting to me. I’m a believer in chasing after your dreams no matter what. And that’s what this tournament symbolizes to me.

“Baltimore will always have a special place in my heart, and I’m excited to bring a tournament like this to this city. Basketball and Baltimore go hand in hand. The perfect match. A city that is all about determination. A city that helped build me.”

The nearby Wizards would seem an attractive destination for Anthony, but they just matched an offer sheet to small forward Otto Porter Jr. (four years, $106 million). The Post has reported the Knicks want Anthony to expand his wish list and Oklahoma City and Portland reportedly are interested.

Hooking up with his buddies Chris Paul and James Harden in Houston has become Anthony’s priority. Even the prospect of playing again for former Knicks coach Mike D’Antoni has not deterred Anthony, who rebelled against his speed-ball offense and reliance on Jeremy Lin, leading to the coach’s resignation in 2012.

Dan D’Antoni, the former Knicks assistant, told The Post on Monday his brother will be able to move on from the rancor in New York.

“There were a lot of things that went wrong, but Carmelo is a heckuva player,’’ Dan D’Antoni said. “All I’m saying is Mike’s a good person. He understands people change, things change. Two things you can’t deny: Mike’s a helluva coach. Carmelo is a very good player. If those two see eye-to-eye, Mike and I are always optimistic things are meant to be. The next day is going to be better than the day before.”

The Rockets dangled Ryan Anderson’s contract in multi-team packages but found no takers.

General manager Daryl Morey stockpiled a handful of non-guaranteed pacts to apply to an Anthony trade for mathematical purposes but Sunday released one of those players, Jarrod Uthoff, who had $200,000 due this week if he remained on the roster. Shawn Long, Tim Quarterman and Isaiah Taylor are still non-guaranteed chips on Houston’s roster.

Anthony can only hope those guys will be on the move soon.
