+On Windows & macOS we always statically link libsqlcipher for it is not generally available.
+On Linux by default we will use a system package, on debian & ubuntu this is `libsqlcipher0`,
+but this is problematic for some other packages. 
+By including `SQLCIPHER_STATIC=1` in the build environment, the build scripts will statically link sqlcipher,
+note that this will want a `libcrypto1.1` shared library available in the system.
