Try this:
cmake --help-command FIND_FILE
....
   FIND_FILE(
             <VAR>
             name | NAMES name1 [name2 ...]
             PATHS path1 [path2 ... ENV var]
             [PATH_SUFFIXES suffix1 [suffix2 ...]]
             [DOC "cache documentation string"]
             [NO_DEFAULT_PATH]
             [NO_CMAKE_ENVIRONMENT_PATH]
             [NO_CMAKE_PATH]
             [NO_SYSTEM_ENVIRONMENT_PATH]
             [NO_CMAKE_SYSTEM_PATH]
            )
...
   specified after the PATHS argument.  If ENV var is found in the PATHS
   section the environment variable var will be read and converted from a
   system environment variable to a cmake style list of paths.  For
   example ENV PATH would be a way to list the system path variable.  The

You want:
FIND_FILE( MYVAR "boost/shared_ptr.hpp" PATHS ENV INCLUDE)
