That was my guess as well, but it appears from the results above that
the autotools-based build system for Tcl independently detects the Cygwin
platform and demands you use the win subdirectory in that case.
Therefore here is my guess for what might work:
Current logic in tcl/CMakeLists.txt
if(MSYS_PLATFORM)
set(source_PATH ${source_PATH}\unix)
else(MSYS_PLATFORM)
set(source_PATH ${source_PATH}/unix)
endif(MSYS_PLATFORM)
==>
if(MSYS_PLATFORM)
set(source_PATH ${source_PATH}\\win)
elseif(CYGWIN)
set(source_PATH ${source_PATH}/win)
else
set(source_PATH ${source_PATH}/unix)
endif(MSYS_PLATFORM)
That first change to \\win is irrelevant to you since MSYS_PLATFORM is
OFF, but nevertheless that is my guess for what might work in the
MinGW/MSYS case.
Of course, for both the MinGW/MSYS and Cygwin platforms we are both
guessing here because we are both unfamiliar with the autotools build
for Tcl on either of those platforms, but the above change is worth a
try.
If the above guess doesn't work on Cygwin, then I suggest you put this aside
for the time
being and test other components of the -DBUILD_THE_BUILDTOOLS=ON
case to see what works and what doesn't on Cygwin.
Then move on to the (default) -DBUILD_THE_BUILDTOOLS=OFF case for
epa_build which assuming you have set up your setup/setup_cygwin file
correctly (see setup/setup_linux for a template of how to set up that
file) will use the -DBUILD_THE_BUILDTOOLS=ON results when they are
available but otherwise use the system versions (e.g. for Tcl and Tk).
