Per-source copyright/license notice headers that spell out copyright holder names and years are hard to maintain and often out-of-date or plain wrong. Precise contributor information is already maintained automatically by the version control tool. Ultimately it is the receiver of a file who is responsible for determining its licensing status, and per-source notices are merely a convenience. Therefore it is simpler and more accurate for each source to have a generic notice of the license name and references to more detailed information on copyright holders and full license terms. Our `Copyright.txt` file now contains a list of Contributors whose names appeared source-level copyright notices. It also references version control history for more precise information. Therefore we no longer need to spell out the list of Contributors in each source file notice. Replace CMake per-source copyright/license notice headers with a short description of the license and links to `Copyright.txt` and online information available from "https://cmake.org/licensing". The online URL also handles cases of modules being copied out of our source into other projects, so we can drop our notices about replacing links with full license text. Run the `Utilities/Scripts/filter-notices.bash` script to perform the majority of the replacements mechanically. Manually fix up shebang lines and trailing newlines in a few files. Manually update the notices in a few files that the script does not handle.

|
|
|
|
// 1. Compiler compiles the application and generates the *.obj files.
|
|
// 2. An empty manifest file is generated if this is a clean build and if
|
|
// not the previous one is reused.
|
|
// 3. The resource compiler (rc.exe) compiles the *.manifest file to a
|
|
// *.res file.
|
|
// 4. Linker generates the binary (EXE or DLL) with the /incremental
|
|
// switch and embeds the dummy manifest file. The linker also generates
|
|
// the real manifest file based on the binaries that your binary depends
|
|
// on.
|
|
// 5. The manifest tool (mt.exe) is then used to generate the final
|
|
// manifest.
|
|
|
|
// If the final manifest is changed, then 6 and 7 are run, if not
|
|
// they are skipped, and it is done.
|
|
|
|
// 6. The resource compiler is invoked one more time.
|
|
// 7. Finally, the Linker does another incremental link, but since the
|
|
// only thing that has changed is the *.res file that contains the
|
|
// manifest it is a short link.
|
|
|
|
// Create a resource file referencing the manifest.
