Downgrade build system requirements to allow building on Ubuntu 20.04 about sqsh-tools

[Gottox]

I just looked at the source. meson-0.57 is only needed for -Ddoc=true and for -Dtest=true. I'm removing the min requirement.

Note the issue here is that meson compile was implemented in meson 0.54.0.

All it does anyway is immediately run ninja on Linux, but it will also check if you are using Windows' msbuild and run that instead as necessary. That's actually the original reason meson compile was created, it serves as a small wrapper script that detects whether you use the vs, xcode, or ninja backends and then runs the correct command. Easier to describe in a README, apparently.

On meson 0.53.0, since it isn't parsed as a "compile" command, meson thinks you meant to run meson ./compile, i.e. "assume that the implicit subcommand is setup, then create a new build directory using the current working directory as a source directory". Current versions of meson will actually warn you that it's deprecated to not include the word "setup", because we want to drop that unintuitive behavior... but that will take a while until meson 0.64.0 is the oldest version of meson distributed in LTS distros.

Have you tested it? This is what I get...

           meson setup build \
            -Dwerror=false \
            -Dexamples=false  \
            -Dcurl=disabled  \
            -Dzlib=enabled \
            -Dlz4=disabled \
            -Dlzma=disabled  \
            -Dzstd=enabled  \
            -Dthreads=enabled \
            -Ddoc=false \
            -Dtest=false
           cd build
           ls
           meson compile

Maybe you can change

to runs-on: ubuntu-20.4 to test?

I tried ninja instead of meson compile, that worked for me.

I can confirm that. Thanks! 👍
