Question

我正在尝试收集和处理顶级目录中的所有源文件，以处理变量未传递到子目录的事实。我拼凑了以下CMakeLists.txt文件：

    cmake_minimum_required(VERSION 2.8)
project(main)
enable_language(Fortran)
enable_testing()

set (CMAKE_Fortran_COMPILER ifort)
set (CMAKE_Fortran_FLAGS " -g -C -fixed")
set (CMAKE_Fortran95_FLAGS " -openmp ")

# function to collect all the sources from sub-directories
# into a single list
function(add_sources)
  get_property(is_defined GLOBAL PROPERTY SRCS_LIST DEFINED)
  if(NOT is_defined)
    define_property(GLOBAL PROPERTY SRCS_LIST
      BRIEF_DOCS "List of source files"
      FULL_DOCS "List of source files to be compiled in one library")
  endif()
  # make absolute paths
  set(SRCS)
  foreach(s IN LISTS ARGN)
    if(NOT IS_ABSOLUTE "${s}")
      get_filename_component(s "${s}" ABSOLUTE)
    endif()
    list(APPEND SRCS "${s}")
  endforeach()
  # append to global list
  set_property(GLOBAL APPEND PROPERTY SRCS_LIST "${SRCS}")
endfunction(add_sources)



add_sources(SRCS main.f95)
add_subdirectory(sub)

# preprocess sources
set(PREP_SRCS)
get_property(SRCS GLOBAL PROPERTY SRCS_LIST)
foreach(s IN LISTS SRCS)
  file(RELATIVE_PATH rs "${CMAKE_CURRENT_SOURCE_DIR}" "${s}")
  string(REGEX REPLACE "f95$" "f" o "${CMAKE_CURRENT_BINARY_DIR}/${rs}")
  add_custom_command(
    OUTPUT "${o}"
    COMMAND ${CMAKE_COMMAND} -E copy "${s}" "${o}"
    DEPENDS "${s}"
    if(${s} MATCHES "f95$")
      set_source_files_properties( ${o} PROPERTIES 
     COMPILE_FLAGS ${CMAKE_Fortran95_FLAGS})
     endif(${s} MATCHES "f95$")
    COMMENT "Creating ${o}"
    VERBATIM
    )
  list(APPEND PREP_SRCS "${o}")
endforeach()

message(${PREP_SRCS})

add_executable(main ${PREP_SRCS})


SET_TARGET_PROPERTIES(main PROPERTIES LINKER_LANGUAGE Fortran)
SET_TARGET_PROPERTIES(main PROPERTIES 
LINK_FLAGS " ")

并在sub /

中

 add_sources(SRCS saxpy2.f95 saxpy_noomp.f)

但显然缺少一些微妙的东西。 TIA
