+  # Above, we set the cache var CMAKE_PREFIX_PATH=install and the env var

+  # (Note that we have to set the cache var CMAKE_PREFIX_PATH=install to put
+  # install/ in the search path ahead of install_tpl1/ for this simulation
+  # since CMAKE_INSTALL_PREFIX, which initializes CMAKE_SYSTEM_PREFIX_PATH, is
+  # searched after the env var CMAKE_PREFIX_PATH.)

+  # This test simulates the situation in bug #427 where CMAKE_INSTALL_PREFIX
+  # (which initializes CMAKE_SYSTEM_PREFIX_PATH) is searched before PATH and
+  # HDF5Config.cmake was getting found in CMAKE_INSTALL_PREFIX from a prior
+  # install of Trilinos.  But since I don't want to mess with PATH for this
+  # test, I just want to have find_package() search install/ before in
+  # searches install_tpl1/ to simulate that scenario.  This test ensures that
+  # find_package(Tpl1) will not does not find Tpl1Config.cmake just because
+  # CMAKE_PREFIX_PATH is in the search path.
