I'm not quite sure which component this fits in – I chose "Project Management", feel free to correct.

1. Right click on Project, choose "Add Library"
2. Select External Library and click Next.
3. Choose a static library located on a different drive than the project.

This wizard adds the following wrong path to the .PRO file (notice the "$$PWD/D:/"):

INCLUDEPATH += $$PWD/D:/MyLib/include
DEPENDPATH += $$PWD/D:/MyLib/include

win32:CONFIG(release, debug|release): PRE_TARGETDEPS += $$PWD/D:/MyLib/lib/mylib.lib
else:win32:CONFIG(debug, debug|release): PRE_TARGETDEPS += $$PWD/D:/MyLib/lib/mylibd.lib

And the build error:

Error: dependent 'C:\MyProj\D:\MyLib\lib\mylib.lib' does not exist.
