The FILE GLOB could do the same trick as you suggest:
"FILE(GLOB qwt_files ${qwt_dir}/include/qwt*/qwt_plot.h)"

I tried to write a patch which uses exactly that.
It tries to locate the header files in:
/usr/local/qwt*/include
/usr/local/include/qwt*
/usr/qwt*/include
/usr/include/qwt*
/opt/local/qwt*/include
/opt/local/include/qwt*
/sw/local/qwt*/include
/sw/local/include/qwt*
Furthermore, the libraries are searched in the same order. So if I
have the packaged version for qwt in /usr/include/qwt5 and I have a
manually compiled qwt in /usr/local/qwt-6.0.2-svn, it prefers the
manually compiled version, and makes sure that it will then search the
libraries in exactly the same order. On 64bit machines, the lib64 will
be preferred over lib.
This patch is pure cmake language, so it should not break on windows.
Furthermore, no maintenance should be needed with new versions of qwt.
