The NVHPC packages bundle the CUDA math libraries in a sibling
directory (`math_libs`) instead of in with the rest of the
cuda libraries.
Depending on the NVHPC package the math_libs folder can have
versioned subdirectories, therefore we prefer finding the
same versions as the CUDA Toolkit and falling back to the
latest when not possible.
The search logic for the IAR linker, librarian and related tools is
moved from `Modules/Compiler/IAR-FindBinUtils.cmake` to
`Modules/CMakeFindBinUtils.cmake` by introducing an new elseif block
for the IAR toolchain.
The search logic was refactored to omit repeating itself.
Fixes: #22425
Depending on the CUDA installation the nvvm/libdevice folder can
be in different locations. Since `nvcc` outputs the expected location use that when possible.
There is no `NAME` option. It should be `NAMES`. The call worked
with `NAME` only due to old `find_program` signature compatibility.
After this, the `find_program` call works even with PATHS removed
(on non-Windows systems where this PATHS is not needed).
Revert commit 0665d9092e (CMakeDependentOption: Allow parentheses in the
depends string, 2021-06-13, v3.21.0-rc1~32^2). It broke existing use
cases with parentheses in regular expressions. Also add a test for this.

IAR is available for both Linux and Windows OSes. Moreover,
binaries `*.exe` could be called from a Linux box, or vice versa.
See also commit 01a4eec446 (IAR: Changes required for Linux,
2019-04-25, v3.15.0-rc1~185^2).

Setting `CMAKE_EXECUTABLE_FORMAT` as a normal variable is unnecessary
because setting it as a cache entry already makes the value visible to
the calling scope.

While the flag tables for C and C++ were generated from MSBuild `.xml`
files, the CSharp flag tables were written by hand. Copy the `v142`
flag table to use for the `v143` toolset.
Update the logic that converts a `try_compile` result from a cache
entry to a normal variable to tolerate an existing normal variable
under CMP0126 NEW behavior. Otherwise the `try_compile` result
is ignored because CMake uses the false value of the normal variable,
and CMake incorrectly reports that the compiler does not work.
This went unnoticed for some languages (e.g. C and CXX) because the
check for a working compiler is skipped if ABI detection works.
It does affect other languages (e.g. CSharp).

With Cray compiler wrappers (implicitly tested on OLCF Spock) the
BLAS and LAPACK libraries are automatically linked as necessary through
the wrapper script and programming environment. With this change, the
configure output is:
```
-- Found BLAS: implicitly linked
<snip>
-- Found LAPACK: implicitly linked
```
rather than
```
-- Found BLAS: 1
<snip>
-- Found LAPACK: LAPACK_LIBRARIES-PLACEHOLDER-FOR-EMPTY-LIBRARIES
```
Given the compiler to use, `CMakeFindBinUtils.cmake` automatically
determines a number of tools including linker (CMAKE_LINKER) and archiver
(CMAKE_AR) and stores them in a generated file `CMakeCCompiler.cmake` as
non-CACHE entries. The compiler-specific ARMClang.cmake then tries to
override CMAKE_LINKER and CMAKE_AR as CACHE entries.
Following the introduction of CMP0126, which is set to NEW in the test
for a working compiler, setting a CACHE entry does not replace a normal
entry of the same name anymore, resulting in a failed test due to wrong
linker and archiver.
To fix this, set CMAKE_LINKER and CMAKE_AR for ARMClang directly in
`CMakeFindBinUtils.cmake` as is done for other compilers. Check
for them in `ARMClang.cmake` to safeguard cases when a project explicitly
includes `ARMClang.cmake` prior to compiler determination (which some
projects do to work around other problems in older CMake versions).
Tell `pkg-config --libs` not to filter out `-L` flags for entries of
`PKG_CONFIG_SYSTEM_LIBRARY_PATH` (and `LIBRARY_PATH` for `pkgconf`).
We should always search everywhere the `.pc` file expects.

Cray traditionally does not ship mpicc/mpic++ compiler wrappers.
Due to that, the traditional CMake logic to find MPI is to *only*
support MPI on Cray systems if either
1. Cray Wrappers are used for compiling, or
2. an auxiliary MPI executable is found.
On many new Exascale prototypes, using the Cray wrappers for develop
work is extremely painful. Vendors such as AMD and integrators such
as HPE seem not to go well in lock-step in Cray programming envs,
making offloading with Cray wrappers too challenging. On the other
hand, using the working experimental Vendor compilers works well,
as long as one does not need MPI.
Extend the fallback MPI search logic by also interrogating the
CC/cc/ftn binaries if found for their MPI flags. This does not
change existing logic, i.e. using the Cray wrappers directly, but
provides an additional way to get MPI programs compiled on Cray.

When a user provides `CPACK_DEBIAN_PACKAGE_CONTROL_EXTRA` or
`CPACK_DEBIAN_<comp>_PACKAGE_CONTROL_EXTRA` variables in
`CMakeLists.txt` and the package contains dynamic libraries, the
`CPackDeb.cmake` sets `CPACK_ADD_LDCONFIG_CALL` to `1`. Later it
analyzes if defaulted `postinst`/`postrm` should be generated trying to
check if the user provides any in `CPACK_DEBIAN_PACKAGE_CONTROL_EXTRA`
variable. However, the `foreach` loop uses the invalid variable
`PACKAGE_CONTROL_EXTRA` instead, so these files gonna be overridden.
Fix the variable name.

Logic added by commit 4c74c86f40 (FindBLAS/LAPACK: Add support for the
Fujitsu SSL2 library, 2021-01-27, v3.21.0-rc1~402^2~1) accidentally
expressed a boolean condition without proper grouping. The pattern was
then copied by commit 2c9e623e31 (Find{BLAS,LAPACK}: Add support for the
NVHPC LAPACK library, 2021-05-05, v3.21.0-rc1~192^2). The resulting
logic incorrectly tries Fujitsu and NVHPC vendors even after results are
found from another vendor, and then erases those. Fix the grouping.

Currently, this feature is only supported on ELF platforms. So, the property
LINK_WHAT_YOU_USE will be ignored for other plateforms.
Moreover, flags and commands are now controled by CMake variables.
