This is strange - I don't use slackware, but do you have same setup on both
x86 and amd64?

The file gets generated by

##### config.ci (generated) #####################

add_custom_command( OUTPUT config.ci
  COMMAND perl -w ${CMAKE_SOURCE_DIR}/tdm/confproc.pl
${CMAKE_SOURCE_DIR}/tdm/config.def config.ci
  DEPENDS ${CMAKE_SOURCE_DIR}/tdm/confproc.pl
${CMAKE_SOURCE_DIR}/tdm/config.def )

perhaps it fails on dependency
