There is no integration of Lua's source code in my outline.  It is
only a change to the CMake language lexer/parser to handle Lua-style
long-bracket syntax.  For example:

file(WRITE myfile.txt [====[
This is the first line!
Arbitrary content without:
 - ${variable} evaluation
 - \-escapes
 - "-quoting
]====])

instead of

file(WRITE myfile.txt "This is the first line!
Arbitrary content without:
 - \${variable} evaluation
 - \\-escapes
 - \"-quoting
")

It will also support long-bracket comments, e.g.

#[========[
This is a multi-line comment that can contain arbitrary text except
for the close bracket of equal length.  It is great for long
explanations, copyright notices, and commenting out large blocks
of code.  The closing bracket does not need to start in #, but if
it does then a one-character change to the opening bracket to be
"##[========[" would enable the entire block and the ending line
would be a normal one-line comment.
#]========]
