cmake build of hdf5 installs mirror_server{,_stop} when VFD is not built #4984
Description
Describe the bug
When doing a cmake build, the mirror_server{,_stop} utilities are installed even wihen the mirror VFD is not built. This seems to be because the former is triggered by HDF5_BUILD_UTILS which is on by default, not HDF5_BUILD_MIRROR_VFD.
Expected behavior
mirror_server and mirror_server_stop are not installed when HDF5_BUILD_MIRROR_VFD is OFF.
Platform (please complete the following information)
- HDF5 version 1.14.5
- Build system - cmake
