Subject: cmake: set version for `project()` and add CPack support
X-Git-Tag: curl-8_11_0~120
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=fbc0da376f52072565a6c2f146d3bc6c857e1917;p=thirdparty%2Fcurl.git

cmake: set version for `project()` and add CPack support

Note: the version like `8.11.0-DEV` is not a valid version for
`project()`, so need to extract the major, minor and patch parts.

Previous, manual, `CURL_VERSION` macro is defined by `project()`
after this patch, so rename existing `CURL_VERSION*` variables to
`_curl_version*`.

Closes #15281
