dependencyCache.h invalid call to std::bool::store()

[jfpanisset]

In pxr/exec/ef/dependencyCache.h :

class _Entry {
public:
...
    void Invalidate() {
        valid.store(std::memory_order_relaxed);
    }
...
    // Set to false when the entry is fully invalid.
    std::atomic<bool> valid;
};

gcc 14.2 complains of no matching signature when Invalidate() calls valid.store(std::memory_order_relaxed) since according to:

https://en.cppreference.com/w/cpp/atomic/atomic/store.html

the signature since C++ 11 is:

void store( T desired, std::memory_order order = std::memory_order_seq_cst)

Changing Invalidate() to:

    void Invalidate() {
        valid.store(false, std::memory_order_relaxed);
    }

allows the code to compile, and the comment // Set to false when the entry is fully invalid. seems to indicate that is the correct thing to do, but I know nothing of this code.

Also it seems that dependencyCache.{h,cpp} is only compiled under specific circumstances, I'm switching my build hardness from an ad-hoc Bash script to a Conan recipe, but I'm not clear which specific option I am passing to cmake which is forcing this code to get compiled.
