I am using the excellent nlohmann::json library. I can see that it has an option for disabling implicit conversion which is recommended.

First I tried to set this option via:

set(JSON_ImplicitConversions OFF)
find_package(nlohmann_json 3.10.3 REQUIRED)

But that did not seem to have any effect. I then tried using fetch_content:

set(JSON_ImplicitConversions OFF)
FetchContent_Declare(json
    GIT_REPOSITORY https://github.com/nlohmann/json
    GIT_TAG v3.11.3
)
FetchContent_MakeAvailable(json)

And this gave the required effect. I much prefer the find_package. Am I using it wrong? Is it not possible to set options in this way with find_package?
