openvdb: find_packge(OpenVDB) failed after brew install openvdb

So I 'm using openvdb as a module of my project. Everything goes fine until I add afind_package(OpenVDB REQUIRED) command in my CMakeLists.txt. The error message is:

CMake Error at xxx/xxx/CMakeLists.txt:8 (find_package):
  By not providing "FindOpenVDB.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "OpenVDB", but
  CMake did not find one.

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

    OpenVDBConfig.cmake
    openvdb-config.cmake

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

Other modules, like GLEW can be found as expected after installed by homebrew
