You can use the ccmake dialog to edit these paths and correct them.  One
of the things on our todo list for CMake is to improve the find support
for Tcl and Python to help avoid finding pieces from different
installations.

Make sure TCL_LIBRARY and the like are set to your libraries and not the
frameworks.

I think your Tk installation must be installed in some special way to
support X-windows on the Mac.  I'm not sure what this means, though.
Hopefully someone else can answer this.
