I don't think you can change permission in a portable manner at CMake time.

You may set permission using PERMISSIONS option of the
CMake INSTALL command (thus at install time),
however I guess you'd like to use
your generated scripts during build time and not after install time?

If you want to run your script at either CMake or build time using
execute_process and/or add_custom_command keep reading...

If you know that your script in a tcl one AND you must run it at CMake
or build time then you can explicitely call

tcslh <yourscript>

if you do that you can do:

FIND_PACKAGE(Tclsh)

${TCL_TCLSH} should contain a valid tclsh interpreter.
