I am trying to write a cmake function which imitates the functionality
of wc -l for unix. However i can't seem to be able to figure out how to
store the result into the variable which is passed to the function.
function (wcl fileName lines)
file(READ ${fileName} fileData)
if(fileData)
string(REGEX MATCHALL "\n" lines ${fileData})
list(LENGTH lines lines)
endif(fileData)
endfunction()
i call the function as
wcl (${fileName} fileLen)
and printing it gives no output
message("${fileLen}")
What am i doing wrong ?
Regards
Johny
