Describe the bug

The cmake setup hook breaks with __structuredAttrs = true.

Steps To Reproduce

Write a derivation that uses cmake with __structuredAttrs = true and set cmakeFlags to a list with >1 element.
The build hook always treats $cmakeFlags as a normal variable, so it uses only the first array element.

Expected behavior

The flags get passed to cmake

Screenshots

If applicable, add screenshots to help explain your problem.

Additional context

Solution used in the npm hook:

Workaround: use cmakeFlagsArray instead.
