Library woes - can't be found

[waynew]

Still trying to get this external library working.
Here is the pro file entry:

LIBS += -L"C:\mingw\msys\1.0\home\wayne\tqsllib\lib"
LIBS += -llibtqsllib

LIBS += -L"C:\mingw\msys\1.0\home\wayne\tqsllib\lib"
LIBS += -llibtqsllib

To copy to clipboard, switch view to plain text mode 

And here is the compile error message:
c:/qt/2010.02.1/mingw/bin/../lib/gcc/mingw32/4.4.0/../../../../mingw32/bin/ld.exe: cannot find -llibtqsllib

And here is the line from the Makefile.Release:
LIBS = -L'c:/Qt/2010.02.1/qt/lib' release/hrlogger_res.o -LC:\cpp\qt_projects\hrlogger_development\debug\bui ld\lib\qserialdevice\release -LC:\cpp\qt_projects\hrlogger_development\debug\bui ld\lib\qserialdevicewatcher\release -lqserialdevice -lqserialdevicewatcher -LC:\mingw\msys\1.0\home\wayne\tqsllib\lib -llibtqsllib -lQtHelp4 -lQtTest4 -lQtSql4 -lQtXml4 -lQtGui4 -lQtNetwork4 -lQtCore4

And the system path variable includes the path to libtqsllib.a
And I have verified the file is there, with that name.

Any ideas?
