Can we split out the debian Ci build fix in a single commit, please? This is not related to meson build. Or push it directly to master, it's tested here ;-)

@raveit65 #393

[raveit65]

Some warnings with meson setup command.

data/meson.build:7: WARNING: Project targets '>=0.46.0' but uses feature introduced in '0.50.0': install arg inconfigure_file.
Configuring org.mate.power-manager.gschema.xml.in using configuration
data/meson.build:20: WARNING: Project targets '>=0.46.0' but uses feature introduced in '0.50.0': install arg in configure_file.

Meson install gives me an error.

[124/149] Generating policy/org.mate.power.policy with a custom command
ninja: build stopped: subcommand failed.

[zhuyaliang]

@raveit65 Please test again

[raveit65]

Do you see this warning or is this fedora related?

WARNING: find_library('libm') starting in "lib" only works by accident and is not portable
Library libm found: YES

I get an install warning.

Compiling GSchema
No schema files found: doing nothing.

It isn't compiled:

[rave@mother mate-power-manager-dist]$ ls -la /tmp/meson_dir/share/glib-2.0/schemas/
total 20
drwxr-xr-x 2 rave rave    60 Oct 23 14:59 .

-rw-r--r-- 1 rave rave 19166 Oct 23 14:57 org.mate.power-manager.gschema.xml.in

Should be look like this:

[rave@mother mate-power-manager-dist]$ ls -la /tmp/make_dir/share/glib-2.0/schemas/
total 28
drwxr-xr-x 2 root root    80 Oct 23 14:54 .

[raveit65]

Can you please rebase with master to get debian build working.

[raveit65]

Not sure if this is a problem. icon-cache isn't updated in

@raveit65 Please test again Update cache when DESTDIR is not set

[mate@mouse mate-power-manager]$ cat meson_post_install.sh 
#!/bin/sh
if [ -z $MESON_INSTALL_PREFIX ]; then
    echo 'This is meant to be ran from Meson only!'
    exit 1
fi

if [ -z $DESTDIR ]; then
    echo 'Compiling GSchema'
    glib-compile-schemas "$MESON_INSTALL_PREFIX/share/glib-2.0/schemas"
    echo 'Updating icon cache'
    gtk-update-icon-cache -qtf "$MESON_INSTALL_PREFIX/share/icons/hicolor"
    gtk-update-icon-cache -qtf "$MESON_INSTALL_PREFIX/share/mate-power-manager/icons/hicolor"
    echo 'Updating desktop database'
    update-desktop-database -q "$MESON_INSTALL_PREFIX/share/applications"

Is this ready to go or should we wait for another review?
