Installation of Cheese

Install Cheese by running the following commands: 

mkdir build &&
cd    build &&

meson setup --prefix=/usr        \
            --buildtype=release  \
            -Dgtk_doc=false      \
            -Dtests=true         \
            ..                   &&
ninja

To test the results, issue: ninja test

Now, as the root user: 

ninja install

Command Explanations

--buildtype=release: Specify a buildtype suitable for stable releases of the package, as the default may produce unoptimized binaries.

-Dgtk_doc=false: This switch prevents the build system from generating and installing the API documentation. Omit this switch if you have GTK-Doc-1.33.2 installed and wish to generate and install the API documentation. Building the documentation is broken due to an incompatibility with gtk-doc.

-Dtests=true: This switch allows building the tests so that the test suite can be run. Remove this switch if you are not going to run the tests.
