cmake-format v0.6.8

There is now an embeded a database of known variables and
properties.cmake-lint uses this database to implement checks on
assignment/use ofvariables that are likely to be typos of a builtin
variable name. There arealso two new configuration options vartags and
proptags that canbe used to affect how the parser and formatter treat
certain variables andproperties.

Line comments within a statement are now consumed the same as line
comments atblock-scope. This means that your multiline mid-statement
comments will bereflowed whereas they would previously have been left
alone.

The CI Build has gotten a little more complicated. Generated
documentationsources are no longer committed to the repository. Instead,
they are pushed toa separate staging repository from which the
read-the-docs pages are built.
