I think you should change `nanoarrow` explicitly to `nanoarrow_static` to be
consistent and then add a `nanoarrow::nanoarrow` alias to it (I assume static
will be the default? Or you could base that on `BUILD_SHARED_LIBS` like this
```cmake
if(BUILD_SHARED_LIBS)
add_library(nanoarrow::nanoarrow ALIAS nanoarrow_shared)
else()
add_library(nanoarrow::nanoarrow ALIAS nanoarrow_static)
endif()
```
This is mostly relevant when nanoarrow is built as a subproject. You could
also add an option that allows toggling the building of either version (gflags
does that). That way I don't have to compile everything twice if I only care
about static.
For packaging the shared bit could be made a component that also changes
which target gets the main alias. (again something gflags does
`find_package(gflags COMPONENTS shared)`
nit: You should be able to create an INTERFACE target for the sources and
use that instead of variables:
https://cmake.org/cmake/help/latest/prop_tgt/INTERFACE_SOURCES.html
I haven't used an interface target but it's a nice solution to avoid raw
variables (which I am always happy about...)
