Shouldn't be this in the

if( BUILD_TZ_LIB )

block?

I would put it in this line:

     if ( USE_SYSTEM_TZ_DB AND NOT WIN32 AND NOT MANUAL_TZ_DB )
         target_compile_definitions( date-tz PRIVATE PUBLIC USE_OS_TZDB=1 )
     else()
          target_compile_definitions( date-tz PUBLIC INSTALL=${USE_CUSTOM_TZDB_INSTALL_PATH} USE_OS_TZDB=0 )
     endif()

Se how I removed the other: INSTALL=. together with USE_OS_TZDB, that is IMHO an error, will not be considered

Oh yeah, I should move it.
