| # --------- |

| # Try to find BZip2 |
| # |
| # Once done this will define |
| # |
| # :: |
| # |
| # BZIP2_FOUND - system has BZip2 |
| # BZIP2_INCLUDE_DIR - the BZip2 include directory |
| # BZIP2_LIBRARIES - Link these to use BZip2 |
| # BZIP2_NEED_PREFIX - this is set if the functions are prefixed with BZ2_ |
| # BZIP2_VERSION_STRING - the version of BZip2 found (since CMake 2.8.8) |
