Building Tk, : fatal error u1050

Hey I m trying to get through installation

I have tcl installed "C:\OpenCASCADE-7.3.0-vc14-64\tcltk-86-64" Now I m at Tk:
I have done "Apply the same steps as described for building Tcl above, with the same INSTALLDIR." executed and I get following error:
" : fatal error U1050:
Failed to find tcl.h.  The TCLDIR macro does not appear correct."
Did i miss something, or doing every step for tk is wrong and i understood if falsly?

From the referred doc for Tk building:

You might need to edit default value of TCLDIR variable defined in (should be not necessary if you unpack both Tcl and Tk sources in the same folder).
