Install Balsa by running the following commands:
mkdir build &&
cd    build &&
meson setup .. --prefix=/usr       \
               --buildtype=release \
               -D html-widget=no   &&
ninja
        This package does not come with a test suite.
          Now, as the root user:
        
ninja install
          -D html-widget=no: This
          option disables building the HTML renderer. If you want the HTML
          renderer to be built, verify that you have WebKitGTK-2.48.5
          installed, and then remove this option.
        
          -D canberra=true: This switch enables
          support for event sounds via libcanberra-0.30.
        
          -D compface=true: This switch enables
          support for using Compface-1.5.2 to compress thumbnails
          for contacts.
        
          -D gcr=true: This switch enables
          support for using libgcr for handling TLS certificates. This
          requires that the Gcr-3.41.2 package is installed, which is part of
          a runtime dependency for libsecret.
        
          -D gss=true: This switch enables
          support for Kerberos authentication. This requires that the
          MIT Kerberos V5-1.22.1 package is
          installed.
        
          -D ldap=true: This switch enables LDAP
          address book support. This requires that the OpenLDAP-2.6.10 package is installed.
