as szip libs references libz as optimized, the REMOVE_DUPLICATES strips zlib out of TLL_LIBS but not its optimized keyword resulting in an invalid list
just list zip before fixes the issue (or removing the REMOVE_DUPLICATES of TLL_LIBS)
re: Issue https://github.com/Unidata/netcdf-c/issues/2190
The primary purpose of this PR is to improve the utf8 support
for windows. This is persuant to a change in Windows that
supports utf8 natively (almost). The almost means that it is
still utf16 internally and the set of characters representable
by utf8 is larger than those representable by utf16.
This leaves open the question in the Issue about handling
the Windows 1252 character set.
This required the following changes:
1. Test the Windows build and major version in order to see if
native utf8 is supported.
2. If native utf8 is supported, Modify dpathmgr.c to call the 8-bit
version of the windows fopen() and open() functions.
3. In support of this, programs that use XGetOpt (Windows versions)
need to get the command line as utf8 and then parse to
arc+argv as utf8. This requires using a homegrown command line parser
named XCommandLineToArgvA.
4. Add a utility program called "acpget" that prints out the
current Windows code page and locale.
Additionally, some technical debt was cleaned up as follows:
1. Unify all the places which attempt to read all or a part
of a file into the dutil.c#NC_readfile code.
2. Similary unify all the code that creates temp files into
dutil.c#NC_mktmp code.
3. Convert almost all remaining calls to fopen() and open()
to NCfopen() and NCopen3(). This is to ensure that path management
is used consistently. This touches a number of files.
4. extern->EXTERNL as needed to get it to work under Windows.
The presence of cmake_policy(CMP0075 required CMake >=3.12, and
errors with older CMake. Since older versions of CMake than 3.12
are already broken with NetCDF and uncommon nowadays, it may be
better to explicitly require 3.12 or newer.
* Add current release note for #2176.
* Add missing note for #951 in release 4.8.0.
* Improve related old note for release 4.4.1. Better consistency with recent updates.
Comment change only. Add one paragraph. Explain the reason for the third argument to H5Pset_libver_bounds. Simplifies experimental code using advanced features.

Provide get/set functions to store global data alignment
information and apply it when a file is created.
The api is as follows:
````
int nc_set_alignment(int threshold, int alignment);
int nc_get_alignment(int* thresholdp, int* alignmentp);
````
If defined, then for every file created opened after the call to
nc_set_alignment, for every new variable added to the file, the
most recently set threshold and alignment values will be applied
to that variable.
The nc_get_alignment function return the last values set by
nc_set_alignment. If nc_set_alignment has not been called, then
it returns the value 0 for both threshold and alignment.
The alignment parameters are stored in the NCglobalstate object
(see below) for use as needed. Repeated calls to nc_set_alignment
will overwrite any existing values in NCglobalstate.
The alignment parameters are applied in libhdf5/hdf5create.c
and libhdf5/hdf5open.c
The set/get alignment functions are defined in libsrc4/nc4internal.c.
A test program was added as nc_test4/tst_alignment.c.
## Misc. Changes Unrelated to Alignment
* The NCRCglobalstate type was renamed to NCglobalstate to
indicate that it represented more general global state than
just .rc data. It was also moved to nc4internal.h. This led
to a large number of small changes: mostly renaming. The
global state management functions were moved to nc4internal.c.
* The global chunk cache variables have been moved into
NCglobalstate. As warranted, other global state will be moved
as well.
* Some misc. problems with the nczarr performance tests were corrected.
