Hi René,

No, I really and truly meant .prl files. These are to qmake what the .pc 
files are to pkg-config. For example, 
<mxedir>/usr/i686-pc-mingw32/lib/QtNetwork.prl contains the line:

QMAKE_PRL_LIBS = -lQtCore -lole32 -luuid -lws2_32 -ladvapi32 -lshell32 
-luser32 -lkernel32 -lz -lz -lssl -lcrypto -lws2_32 -lgdi32 -lcrypt32 -lz

This information is used by qmake when generating makefiles.

Qt's .prl files themselves are generated by qmake, invoked from the Qt 
configure script. The .pro files are of course part of the input for this.
