The problem is that CMake does use the Cygwin version of
tclsh, but the include files found are from the Windows
installation. I include a fragment of the CMakeCache.txt
file to show the problem:

//Path to a program.
TAIL_EXECUTABLE:FILEPATH=/usr/bin/tail.exe

//Path to a file.
TCL_INCLUDE_PATH:PATH=C:/Tcl/include

//Path to a library.
TCL_LIBRARY:FILEPATH=/usr/lib/libtcl.dll.a

//Path to a program.
TCL_TCLSH:FILEPATH=/bin/tclsh

//device used for ctest
TEST_DEVICE:STRING=psc

//Test dynamic drivers
TEST_DYNDRIVERS:BOOL=ON

//Build any of the provided libqsastime test applications.
TEST_QSASTIME:BOOL=OFF

//Path to a file.
TK_INCLUDE_PATH:PATH=C:/Tcl/include

//Path to a library.
TK_LIBRARY:FILEPATH=/usr/lib/libtk.dll.a

//Path to a program.
TK_WISH:FILEPATH=/bin/wish

//use fill_intersection_polygon
USE_FILL_INTERSECTION_POLYGON:BOOL=OFF
   
As you can see, all is Cygwin-related, _except_ the
path to the Tcl include files. I can assure you those
files are present under /usr/include too, with all the
ordinary permissions (-rw-r--r--) and for the correct
version of Tcl (/usr/bin/tclsh returns 8.5.11 and the
tcl.h file contains that very same version number).

Arjen
