[Grammar] Extraposition of an -ing clausal object

[Arnausig]

Dear Sir/Lady,

Why is this sentence incorrect:
"I made it my prime objective settling the matter"
Thank you for your answer

 

[Raymott]

"I made it my prime objective to settle the matter."
"Settling the matter was my prime objective."

 

[Matthew Wai]

Is it correct to say "I made settling the matter my prime objective"?

 

[Raymott]

Yes, it is.
