I have managed to proceed a little bit further, with the following commands:

echo "CMAKE_PREFIX_PATH=$CMAKE_PREFIX_PATH"
echo "CMAKE_INCLUDE_PATH=$CMAKE_INCLUDE_PATH"
echo "CMAKE_LIBRARY_PATH=$CMAKE_LIBRARY_PATH"
echo "CMAKE_PROGRAM_PATH=$CMAKE_PROGRAM_PATH"
mingw32-cmake -D CMAKE_BUILD_TYPE=$BUILD_TYPE \
               -D PKG_OS_ARCH=$ARCH -D CMAKE_INSTALL_PREFIX=$PREFIX \
               -D TCL_INCLUDE_PATH=$CMAKE_INCLUDE_PATH \
               -D TK_INCLUDE_PATH=$CMAKE_INCLUDE_PATH \
               -D TCL_LIBRARY=$CMAKE_LIBRARY_PATH \
               -D TK_LIBRARY=$CMAKE_LIBRARY_PATH ...

Which gave as output:

CMAKE_PREFIX_PATH=/free/cross-compilation-binaries/win32-ix86/tcl/
CMAKE_INCLUDE_PATH=/free/cross-compilation-binaries/win32-ix86/tcl/include
CMAKE_LIBRARY_PATH=/free/cross-compilation-binaries/win32-ix86/tcl/lib
CMAKE_PROGRAM_PATH=/opt/ActiveTcl-8.6/bin
...
CMake Error: The following variables are used in this project, but they 
are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the 
CMake files:
TCL_STUB_LIBRARY (ADVANCED)


How to help cmake to define the stubs library path?
Looking inside the /free/cross-compilation-binaries/win32-ix86/tcl/lib 
folder, the stubs library is named "libtclstub86.a"
