Bindings to [sqlite] for [sqll].
Note that the metadata field of this crate specified which version of sqlite
is provided *if* the `bundled` feature is enabled, like `+sqlite-3.51.2`.
<br>
## Features
* `bundled` - Use the bundled sqlite3 source code. If this feature is not
enabled see the building with system dependencies section below.
* `threadsafe` - Build sqlite3 with threadsafe support. If this is not set
then the `bundled` feature has to be set since we otherwise cannot control
how sqlite is built.
* `strict` - Build sqlite3 with strict compiler flags enabled. This is only
used when the `bundled` feature is enabled.
<br>
## Building
When linking to a system sqlite library there is a minimum required version.
This is specified in the [`sqlite3-version`] file and is checked at build
time.
If the `bundled` feature is not set, this will attempt to find the native
sqlite3 bindings using the following methods:
* Calling `vcpkg`, this can be disabled by setting the `NO_VCPKG` or
`SQLITE3_NO_VCPKG` environment variables.
* Finding the library through `pkg-config`, this can be disabled by setting
or by setting the `SQLITE3_NO_PKG_CONFIG` environment variables.
<br>
## Building under WASM
If the target is is `wasm`, you can set the `SDK_PATH_ENV` to specify an SDK
path to a particular compiler to use when building the wasm bindings. This
is only supported when the `bundled` feature is enabled.
The following environment variables can be set to modify this behavior:
* `SQLL_TARGET` or `TARGET` to specify the build target. You probably want
to set this to something like `wasm32-wasi-unknown`.
* `SQLL_CLANG_PATH` or `CLANG_PATH` to specify a custom path to a clang
compiler installation.
