			We were getting a lot of warnings due to nested `find_package` calls within `Find***.cmake` files. The recommended approach is to use [`find_dependency`](https://cmake.org/cmake/help/latest/module/CMakeFindDependencyMacro.html) in package configuration files. I made this change for all instances. Case mismatches between `Find<Package>.cmake` and calling `find_package(<PACKAGE>`) also lead to warnings. Fixed for `FindPASTIX.cmake` and `FindSCOTCH.cmake`. `FindBLASEXT.cmake` was broken due to calling `find_package_handle_standard_args(BLAS ...)`. The package name must match, otherwise the `find_package(BLASEXT)` falsely thinks the package wasn't found. I changed to `BLASEXT`, but then also copied that value to `BLAS_FOUND` for compatibility. `FindPastix.cmake` had a typo that incorrectly added `PTSCOTCH` when looking for the `SCOTCH` component. `FindPTSCOTCH` incorrectly added `***-NOTFOUND` to include/library lists, corrupting them. This led to cmake errors down-the-line. Fixes #2288.

| # - Find HWLOC include dirs and libraries
 | |
| # Use this module by invoking find_package with the form:
 | |
| #  find_package(HWLOC
 | |
| #               [REQUIRED]) # Fail with error if hwloc is not found
 | |
| #
 | |
| # This module finds headers and hwloc library.
 | |
| # Results are reported in variables:
 | |
| #  HWLOC_FOUND           - True if headers and requested libraries were found
 | |
| #  HWLOC_INCLUDE_DIRS    - hwloc include directories
 | |
| #  HWLOC_LIBRARY_DIRS    - Link directories for hwloc libraries
 | |
| #  HWLOC_LIBRARIES       - hwloc component libraries to be linked
 | |
| #
 | |
| # The user can give specific paths where to find the libraries adding cmake
 | |
| # options at configure (ex: cmake path/to/project -DHWLOC_DIR=path/to/hwloc):
 | |
| #  HWLOC_DIR             - Where to find the base directory of hwloc
 | |
| #  HWLOC_INCDIR          - Where to find the header files
 | |
| #  HWLOC_LIBDIR          - Where to find the library files
 | |
| # The module can also look for the following environment variables if paths
 | |
| # are not given as cmake variable: HWLOC_DIR, HWLOC_INCDIR, HWLOC_LIBDIR
