When nvcomp is found locally print where it is on disk (#434)

This way users always get some console output for where nvcomp is located. We don't remove the `QUIET` request since that would print out the following:

```
  CMake Warning at ..../rapids-cmake/find/package.cmake:125 (find_package):
  By not providing "Findnvcomp.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "nvcomp", but
  CMake did not find one.

  Could not find a package configuration file provided by "nvcomp" (requested
  version 2.6.1) with any of the following names:

    nvcompConfig.cmake
    nvcomp-config.cmake

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