It appears there isn't a better way. I've added the following code to a project file and, after a lot of bug 
hunting, I've managed to force qmake to handle flex & bison files. Yet, this is a flimsy hack that just 
barely manages to successfully generate and compile flex&bison source files.

The code, which was added to qmake's project file, is as follows:
<code>
FlexOutput.target = lex.msh_yy.h
FlexOutput.commands = flex --header-file=lex.msh_yy.h msh.l; mv lex.msh_yy.c lex.msh_yy.c++
FlexOutput.depends = msh.l
FlexOutput.output = lex.msh_yy.c++ lex.msh_yy.h

BisonOutput.target = msh.tab.h
BisonOutput.commands = bison -d --debug msh.y
BisonOutput.depends = msh.y
BisonOutput.output = msh.tab.c msh.tab.h

BisonCompile.target = msh.tab.o
BisonCompile.commands = g++ -c msh.tab.c
BisonCompile.depends = msh.tab.c msh.tab.h
BisonCompile.output = msh.tab.o

OBJECTS += msh.tab.o

QMAKE_EXTRA_TARGETS += FlexOutput BisonOutput BisonCompile
</code>
