Hello build bot (Jenkins), Thomas Heijligen,

I'd like you to reexamine a change. Please visit

to look at the new patch set (#2).

Change subject: ni845x_spi: support building with Meson

ni845x_spi: support building with Meson

This adds a dependency definition for the ni845x library (attempting to
find it in the default install location, allowing the user to specify a
custom path) and adds ni845x_spi as a supported programmer for Meson.

Full functionality has not been verified because the ni845x.h header
shipped with driver version 2022 Q3 causes compile errors relating to
`kNI845XExport` not being defined when built with GCC 12 as shipped by
MSYS2, but this seems to be unrelated to Meson specifically and likely
needs to be fixed more comprehensively through some other method.

Build configuration has been manually inspected to check that the
library is being linked appropriately, since I am unable to compile
the ni845x_spi programmer successfully.
