Compile to 64-bit target in Netbeans

Compile to 64-bit target in Netbeans

I've made a 64-bit application (meaning it uses 64-bit DLLs (OpenCV for
Java to be exact)) in Netbeans and using the inherit Run function works
fine but if I try to build it and run the jar, it gives me this error
java.lang.UnsatisfiedLinkError: no opencv_java246 in java.library.path
at java.lang.ClassLoader.loadLibrary(Unknown Source)
at java.lang.Runtime.loadLibrary0(Unknown Source)
at java.lang.System.loadLibrary(Unknown Source)
at org.chimeras1684.ui.operation.NewDriverUI.main(NewDriverUI.java:43)
I've looked around a bit and it seems that the problem is that Netbeans
run function builds in 64-bit but the build function builds for 32-bit. Is
there a way to force the build to build for 64-bit? Or is the problem
something else that I don't see?
