[Cmake] Problems finding programs on FreeBSD

[Andy Cedilnik]

Hi Richard,

Here is the problem, system may have several alternatives for tcl/tk but
one preferred one. We should use that one.

The solution to your problem of broken OS distributions such as (did you
say) FreeBSD is to not just blindly find an executable tclsh but
actually run it with a simple tcl script. CMake has all mechanisms for
that, somebody just have to sit down and write it.

The script could be something like:

#!/usr/bin/tclsh
puts "TCL version [info tclversion]"
exit

You can then verify in CMake all sorts of things, including, if the
tclsh actually works.
