Enable the attribute "console" of custom_target() introduced in meson
0.48. This allows to get a feedback of what gradle does (which can takes
a very long time).
This produces warnings because we declare to support meson >= 0.37, but
we don't want to stop supporting older versions for that. Older versions
just ignore the option:
> WARNING: Unknown keyword arguments in target scrcpy-server: console
Newer meson versions use it, but warn because we declare supporting
older versions:
> WARNING: Project targetting '>= 0.37' but tried to use feature
> introduced in '0.48.0': console arg in custom_target
Meson does not support conditional branches to suppress such warnings,
so just keep the warnings.
If we don't do this trick, the prebuilt_server will be
../server/[the_user_defined_path]. In general, we will not give an relative path
based on build directory, which leads to wrong prebuilt_server path.
The building error:
ninja: error: '../scrcpy-server-v1.7.jar', needed by
'server/scrcpy-server.jar', missing and no known rule to make it

Expose a 'prebuilt_server' option to pass the path of the prebuilt
binary, so that the build does not require Android SDK.
Usage:
meson builddir -Dprebuilt_server=/tmp/my_prebuilt_server.jar
The custom target used to invoke Gradle from Meson should always
be built, otherwise, the server would not be rebuilt on source changes.
However, when enabling "build_always", gradle is invoked as root on
"sudo ninja install" after "ninja", so it downloads the whole Gradle
world into /root/.gradle.
To avoid the problem, just do not call gradle if the effective user id
is 0.
The client was built with Meson, the server with Gradle, and were run by
a Makefile.
Add a Meson script for the server (which delegates to Gradle), and a
parent script to build and install both the client and the server to the
system, typically with:
meson --buildtype release build
cd build
ninja
sudo ninja install
In addition, use a separate Makefile to build a "portable" version of
the application (where the client expects the server to be in the
current directory). Typically:
make release-portable
cd dist/scrcpy
./scrcpy
This is especially useful for Windows builds, which are not "installed".
