[Trilinos-Users] boost header not found , how to specify boost location

[Orlando.Rivera]

Dear   

I was trying to build trilinos and I got this error 

[ 45%] Building CXX object
packages/stk/stk_util/stk_util/util/CMakeFiles/stk_util_util.dir/Identifier.cpp.o
/naslx/projects/pr28fa/a2815ag/trilinos/trilinos-10.2.1-Source/packages/stk/stk_util/stk_util/util/../../stk_util/util/Identifier.hpp(15): catastrophic error: could not open source file "boost/unordered_set.hpp"
  #include <boost/unordered_set.hpp> // boost 1.36.0 unordered_set not
in the tr1

I was missing boost  , any Idea how to tell to specify boost by building
trilinos .
