   The bitcoin_cv_qt58 variable is used in _BITCOIN_QT_FIND_LIBS_WITHOUT_PKGCONFIG and _BITCOIN_QT_FIND_STATIC_PLUGINS macros.

   But it is set by _BITCOIN_QT_CHECK_QT58 macro only if else branch is executed: https://github.com/bitcoin/bitcoin/blob/b931f61b9ab098ea4ea8fbe4cbf0b03c566c3f63/build-aux/m4/bitcoin_qt.m4#L96-L100

   I think a PR with a fix/for discussion would be a better approach than having an issue open for this. Going to close for now.
