Finally, defining all the variables myself, seems to solve the problem:

mingw32-cmake -D CMAKE_BUILD_TYPE=$BUILD_TYPE \
               -D PKG_OS_ARCH=$ARCH -D CMAKE_INSTALL_PREFIX=$PREFIX \
               -D TCL_INCLUDE_PATH=$TCL_INCLUDE_PATH \
               -D TK_INCLUDE_PATH=$TCL_INCLUDE_PATH \
               -D TCL_LIBRARY=$TCL_LIB_PATH/libtcl${TCL_VERSION}.a \
               -D TK_LIBRARY=$TCL_LIB_PATH/libtk${TCL_VERSION}.a \
               -D 
TCL_STUB_LIBRARY=$TCL_LIB_PATH/libtclstub${TCL_VERSION}.a \
               -D 
TK_STUB_LIBRARY=$TCL_LIB_PATH/libtkstub${TCL_VERSION}.a ...

Now I have only to check what the output of the compiler is... :-)
