re: https://github.com/Unidata/netcdf-c/issues/2294 Ed Hartnett suggested that the netcdf library installation process be extended to install the standard filters into a user specified location. The user can then set HDF5_PLUGIN_PATH to that location. This PR provides that capability using: ```` configure option: --with-plugin-dir=<absolute directory path> cmake option: -DPLUGIN_INSTALL_DIR=<absolute directory path> ```` Currently, the following plugins are always installed, if available: bzip2, zstd, blosc. If NCZarr is enabled, then additional plugins are installed: fletcher32, shuffle, deflate, szip. Additionally, the necessary codec support is installed for each of the above filters that is installed. ## Changes: 1. Cleanup handling of built-in bzip2. 2. Add documentation to docs/filters.md 3. Re-factor the NCZarr codec libraries 4. Add a test, although it can only be exercised after the library is installed, so it cannot be used during normal testing. 5. Cleanup use of HDF5_PLUGIN_PATH in the filter test cases.

# Define a function that attempts to locate a
|
|
# plugin with a given canonical name.
|
|
# Assumptions:
|
|
# 1. plugins is a top-level directory, possibly in "build"
|
|
# Inputs:
|
|
# $1 is the canonical name
|
|
# $2 is 1 if we are running under cmake
|
|
# $3 is 1 if we are running using Visual Studio, blank otherwise
|
|
# $4 is the build type; only used if $3 is 1
|
|
# Outputs:
|
|
# return code is 0 is success, 1 if failed
|
|
# Variable HDF5_PLUGIN_LIB is set to the library file name
|
|
# Variable HDF5_PLUGIN_DIR is set to the absolute path to the
|
|
# directory containing the plugin library file
|
|
# Local variables are prefixed with FP_

# Note: we assume that the use of the CMAKE_BUILD_TYPE
