[CMake] Question about FOREACH

[Dekeyser, Kris]

Hi,

Your FOREACH can work, but you first have to replace the \n chars with ; chars. To illustrate, here's an extract from a macro we use in our build system:

    #--- If config file found, process it
    SET(Configfile "${${ProjectName}_SOURCE_DIR}/adm/config.txt")
    SET(ConfigFileContents)
    
    IF(EXISTS ${Configfile})
      FILE(READ ${Configfile} ConfigFileContents)
    ENDIF(EXISTS ${Configfile})
    
    #--- parse config file
    IF(ConfigFileContents)
    
      #--- Remove newlines
      STRING(REGEX REPLACE "\n" ";" ConfigLines ${ConfigFileContents})
      
      #--- process line by line
      FOREACH(ConfigLine ${ConfigLines})

      [...]

      ENDFOREACH(ConfigLine)
      
    ENDIF(ConfigFileContents)

HTH,
Kris
