# include_regular_expression

Set the regular expression used for dependency checking.

    include_regular_expression(regex_match [regex_complain])

Set the regular expressions used in dependency checking. Only files matching `regex_match` will be traced as dependencies. Only files matching `regex_complain` will generate warnings if they cannot be found (standard header paths are not searched). The defaults are:

    regex_match    = "^.*$" (match everything)
    regex_complain = "^$" (match empty string only)
