Find tclsh
|
|
|
|
This module finds if TCL is installed and determines where the include
|
|
files and libraries are. It also determines what the name of the
|
|
library is. This code sets the following variables:
|
|
|
|
::
|
|
|
|
TCLSH_FOUND = TRUE if tclsh has been found
|
|
TCL_TCLSH = the path to the tclsh executable
|
|
|
|
In cygwin, look for the cygwin version first. Don't look for it later
|
|
to avoid finding the cygwin version on a Win32 build.
