wxmaxima-26.06.2: cmake reports an error

I'm trying to compile wxmaxima-26.06.2, but I get

CMake Error at data/CMakeLists.txt:47 (add_custom_command):
   add_custom_command called with wrong number of arguments.

The corresponding part of data/CMakeLists.txt is

     # Compress man pages
     add_custom_command(
         OUTPUT "${CMAKE_CURRENT_BINARY_DIR}/wxmaxima.1.gz"
         COMMAND gzip -cn9 "${CMAKE_CURRENT_BINARY_DIR}/wxmaxima.1" > 
"${CMAKE_CURRENT_BINARY_DIR}/wxmaxima.1.gz"
         DEPENDS "${CMAKE_CURRENT_BINARY_DIR}/wxmaxima.1"
         COMMENT "Compressing man page"
     )
     add_custom_target(generate_man ALL DEPENDS 
"${CMAKE_CURRENT_BINARY_DIR}/wxmaxima.1.gz")

I use cmake-4.3.3. I cannot understand what's wrong with this 
add_custom_command. Any help?
