[CMake] Reading the content of a file

I can use CONFIGURE_FILE to copy the file, but I have to edit the
content of the file (that goes beyond just replacing VARS in the
file).

I must use a regex to do a string replace. The STRING function can do
this, but only on variables, not files. So I have to read a file into
a variable, change the variable with STRING and finally write it out
into a new file.
