Rationale: since sol2 is a header-only library, some projects might
use it as a private dependency instead of exposing it through their API.
Thus, it is useful to have an option to not install sol2, in order to
reduce the installation size as well as to avoid accidentally exposing
internal dependencies in the top-level project.
The project I work on is a demonstration of how the feature might be
used:
f4a20ec39e/external/CMakeLists.txt (L84)
(mind the different name of the CMake variable, I renamed it to fit the rest
of the sol options convention)
We have an install-check script script which verifies that only expected
headers, libs, targets and docs are exported (the one which are interesting
from users PoV). I wouldn't mind contributing the script as github workflows
if you want to use it as well - please provide feedback if that's desired.
Here is a link to our script for preview:

While modifying the CMake code, I noticed a 4-space instead of TAB in one
place and fixed it to be consistent with the rest of the CMake code.
- Weed out bugs in the numeric checking implementation
- Solve the problem with load_result/protected_function_result/unsafe_function_result being copyable and thus amenable to explosions. Fixes#995.
- Resolve the warning in sol::readonly. Fixes#1000.
- Looke into #1014. Not sure I can help there, honestly; looks like a mix up of multiply-loaded libraries and mixing the two.
