Since: * commite216b9bbd3(cmake: Allow CMAKE_BUILD_TYPE to be set by environment variable, 2021-06-29, v3.22.0-rc1~503^2~1) * commitef56eefc9b(cmake: Allow CMAKE_CONFIGURATION_TYPES to be set by environment variable, 2021-06-29, v3.22.0-rc1~503^2) the environment variables are supposed to provide defaults for settings the user otherwise can control via cache entries. However, they accidentally affect `try_compile` projects too, which are supposed to be programmatically controlled. Fixes: #22935
