[question] build_requires/tool_requires is optimized out even if tools.graph:skip_binaries=False?

[harsszegi]

Hi,

our company packages FMT + SPDLOG via their normal CMake packaging logic, e.g. cmake --install is used to create the package content. SPDLOG has a regular requires() to FMT.

When I compile SPDLOG's test_package, I can clearly see within dependencies FMT, however if I go one level up, and that package consumes SPDLOG via build_requires (or tool_requires, doesn't matter) that doesn't work anymore, FMT is left out, only SPDLOG is pulled in.

However if I pull in SPDLOG via regular requires, it works fine.

Why we use SPDLOG a build_requies / tool_requires in the given package is that SPDLOG is only used when the given package is compiled with unit tests.

Why does build_requires / tool_requires behave differently compared to requires?

Thanks,
