By default gzip embeds a timestamps which makes building it twice
not reproducible, passing -n skips this embedding behaviour.

The expected regression output files all end with a newline. As such, we have to make sure we capture the output from OpenTTD with the last newline intact.
I tried building a tag, and got this error:
CMake Error at cmake/scripts/FindVersion.cmake:85 (string):
string sub-command REGEX, mode REPLACE: regex "^[0-9.]*$" matched an empty
string.
CPack works closely together with CMake to do the right thing in
terms of bundling (called 'package'). This generates all the
packaging we need, and some more.
CMake works on all our supported platforms, like MSVC, Mingw, GCC,
Clang, and many more. It allows for a single way of doing things,
so no longer we need shell scripts and vbs scripts to work on all
our supported platforms.
Additionally, CMake allows to generate project files for like MSVC,
KDevelop, etc.
This heavily reduces the lines of code we need to support multiple
platforms from a project perspective.
Addtiionally, this heavily improves our detection of libraries, etc.
For grfs, it now uses CMake scripts to do its job, and both grf
files are split into their own folder to make more clear what is
going on. Additionally, it no longer builds in-source (although the
resulting grf is copied back in the source folder).
For ob[msg] it now uses CMake scripts to generate the translation
files; the result is no longer stored in-source (but in the build
folder).
Although all files are available to create the GRFs and basesets, it
won't really work till CMake is introduced (which will happen in a
few commits from here)
The tst_stationlist savegame had to be changed to start the correct
AI. In the old setup, all regression AIs had the same name, which
made it impossible to run both regressions in parallel. With the new
setup this is possible.
Although all files are available to run the regression, it won't
really work till CMake is introduced (which will happen in a few
commits from here)
