CMake Warning at CMakeLists.txt:18 (find_package):
  By not providing "FindDOLFIN.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "DOLFIN", but
  CMake did not find one.

  Could not find a package configuration file provided by "DOLFIN" with any
  of the following names:

    DOLFINConfig.cmake
    dolfin-config.cmake

  Add the installation prefix of "DOLFIN" to CMAKE_PREFIX_PATH or set
  "DOLFIN_DIR" to a directory containing one of the above files.  If
"DOLFIN"
  provides a separate development package or SDK, be sure it has been
  installed.

-------------------------------------------------
because of that warning i did the following thing and ran 'make '  command
incidentally make was successful
------------------cmake again for warnings------------------------------

ogin3$ export CMAKE_PREFIX_PATH=$CMAKE_PREFIX_PATH:/home1/03023/rajeswar/

CMake Warning at CMakeLists.txt:37 (add_executable):
  Cannot generate a safe runtime search path for target demo_poisson because
  files in some directories may conflict with libraries in implicit
  directories:

    runtime library [libz.so.1] in /usr/lib64 may be hidden by files in:
      /home1/03023/rajeswar/lib

  Some of these libraries may not be found correctly.
