Yes, the workaround works for me.

However, the exact error is not very enlightening because the error is 
about missing tcl.h and only after adding some tcl.h into header search 
path the build would complain about missing libtcl8.5.so

The problem could be probably easily diagnosed if cmake printed the 
commands it executes but I did not find anything in the cmake help about 
any option to turn it on.
