What is the least complicated way to enable the math functions that come

Solution #1: compile Qt with -system-sqlite (and provide said system sqlite).
Recompiling Qt is something that I try to avoid for now - especially
given that I have "github actions" that make it very easy to install a
given "stock binary Qt release" on the desired integration platform
(that I currently only use for "code analysis", but not actually
building any binaries - "nightly builds" - meant for distribution).
Or in other words: I am trying to keep my "required build setup" as
simple as possible.
So compiling the "SQLite amalgation" sources (sqlite3.h, sqlite3.c)
together with my app and use the *sqlite3_create_function* to add the
desired "sin, cos and pow" etc. functions seems to be "the lesser evil"
- albeit also way more fragile (keyword: "SQLite versions need to
match") than properly recompiling Qt / the Qt SQLite plugin with my own
desired flags.
This applies to ANY use of SQLite, whether you need the math functions or not.
I am not quite sure whether I understand this statement: what exactly
does apply to "any use of SQLite"? For instance I can perfectly use the
provided stock binary Qt SQLite plugin on all platforms (for me:
Windows, macOS, Linux), without having to recompile any Qt related
source code - for as long as I am not using math functions, of course.
So why exactly do you say "whether you need the math functions or not"?
Best,
Oliver
P.S. On a personal note: Hello Thiago! If there is something "more
constant than constexpr in C++", then it is Thiago replying to all sorts
of (broad) topics here on the list (you probably don't remember me, and
that's okay - it's been a while since I have been actively participated
on this list ;))
