Download the rcpp source, build with a tool chain that matches your Qt libraries, and install. This bit has nothing to do with Qt.

In your Qt C++ application use the C++ library.
In Qt Creator
In qmake
In cmake

@ChrisW67

thanks for your answer,
but one more question

1. im install R and RStudio and install.package("Rcpp") in RStudio

2. .pro file
   INCLUDEPATH += "C:\user\AppData\Local\R\win-library\4.2\Rcpp\include"
   like this

3. mainwindow.h
   #include <Rcpp.h>

but i got this message

C:\user\AppData\Local\R\win-library\4.2\Rcpp\include\Rcpp\platform\compiler.h:43: error: C1189: #error: "This compiler is not supported"

@donkey007 What C++ compiler do you use and what C++ compilers are supported by rcpp?
And again: this has nothing to do with Qt, you should consider to ask in a rcpp forum/mailing list and check rcpp documentation.
