Install doesn't install header files

[mborn-adi]

On Windows, install only installs everything except the header files. In CMakeLists.txt, the install is set up like this:

  # Install the library and headers.
  install(TARGETS ${INSTALL_TARGETS} EXPORT ${targets_export_name}
          LIBRARY DESTINATION ${FMT_LIB_DIR}
          ARCHIVE DESTINATION ${FMT_LIB_DIR}
          PUBLIC_HEADER DESTINATION "${FMT_INC_DIR}/fmt"
          RUNTIME DESTINATION ${CMAKE_INSTALL_BINDIR})

But nowhere else are the header files marked "PUBLIC_HEADER".

Adding

set_property(TARGET fmt PROPERTY PUBLIC_HEADER ${FMT_HEADERS})

in line 289 right after

add_library(fmt::fmt ALIAS fmt)

does just that. But cmake is not my strongest suit.

I was able to repro this on macOS and it looks like a recent regression related to modules work.

I am getting this today with Fedora Linux.
