I'm trying to build qwt on a MAC and for some reason, after I do the build I don't get the qwt library, only the qwt_designer_plugin.

I was able to get the qwt library from the same tar file when building on Windows and CentOS7 but not MAC.

Download the 6.1.5 qwt tar file.
Extract the tar file
qmake qwt.pro
sudo make install

I get one library libqwt_designer_plugin.dylib but not libqwt.dylib which is what I need. I'm trying to integrate with QtCreator and running Qt 5.15.
I'm running on MAC OS Catalina 10.15.7

Can someone please tell me what I'm doing wrong?
