Clean up meson.build slightly and add a section to the top to describe what I want to do so I can ask people.

# Here's the overall idea: the build syntax would be something like
|
||||
# $ meson setup build \
|
||||
# [--buildtype=debug|release] \ (core option, default debug)
|
||||
# [--default_library=static|shared] \ (core option, default shared)
|
||||
# [--b_sanitize=whatever]
|
||||
# It turns out that I wouldn't really need any custom options; go figure.
|
||||
# I'm not sure how to allow building 32-bit instead of 64-bit with meson.
|
||||
# I'd also like all the outputs to appear in a folder out/ in the build folder.
|
||||
# I'd also like to be able to omit the library's dependency libraries in the executables if building a shared library, as those are not required in that case; I'd need to require them in a static library.
|
||||
# And for Windows, the shared library (but not shared executables) needs an additional resource file, and the static executables (but not the static library) need a *different* resource file. (Windows static libraries can't contain resources anyway; the linkers will just ignore the resource objects.)
