Antonio Sanchez 1cdec38653 Fix cmake warnings, FindPASTIX/FindPTSCOTCH.
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 BLAS EXTENDED for MORSE projects: find include dirs and libraries
#
# This module allows to find BLAS libraries by calling the official FindBLAS module
# and handles the creation of different library lists whether the user wishes to link
# with a sequential BLAS or a multihreaded (BLAS_SEQ_LIBRARIES and BLAS_PAR_LIBRARIES).
# BLAS is detected with a FindBLAS call then if the BLAS vendor is Intel10_64lp, ACML
# or IBMESSLMT then the module attempts to find the corresponding multithreaded libraries.
#
# The following variables have been added to manage links with sequential or multithreaded
# versions:
# BLAS_INCLUDE_DIRS - BLAS include directories
# BLAS_LIBRARY_DIRS - Link directories for BLAS libraries
# BLAS_SEQ_LIBRARIES - BLAS component libraries to be linked (sequential)
# BLAS_PAR_LIBRARIES - BLAS component libraries to be linked (multithreaded)
