[Insight-developers] CMake changes

[Bill Hoffman]

I have just checked in some changes to CMake that allow the use
of a cache file.  This will require that you re-run configure for Insight.
The cache file is written into the object directory of the build.
The windows GUI, pops up notepad now so, you can change values in the cache.
Right now, for insight there are no values, but soon, the testing stuff
should have some things in it, like TCLSH=/path/to/tcl, etc..
For unix, when you run configure for the first time, it will generate and
dump the cache to the screen at the end of the configure run.
You can then edit the file with emacs and the new values should be picked up
by cmake, after the next make.

For those using CMake in a different project, a new configure.in.sample
file can be found in the CMake directory.   You will need to use it for the
configure.in of the project using CMake.
