Yes. You are on the right track for hand-specifying all versions, and
I assume that works for your rather specialized case where you are
attempting to build PLplot on a computer with no valid display.
If you do not specify the versions by hand, the cmake command follows
the normal CMake find rules (as affected by the set of environment
variables you give it) to find Tcl, Tk, Itcl, Itk, and Iwidgets, and
it is necessary/desirable to do sanity checks for version consistency.
Those sanity checks test whether wish and tclsh give the same "package
require" version results for Tcl and also there is a similar "package
require" check for a consistent Tk version.
Of course, such simple "package require" command results should not
need a display so I am wondering if there is a way to obtain such
results under wish when there is no display? Could you check with
Fedora experts if that is possible?
If so, then you would not have to specify versions by hand like you
do above.
