Usage:
  ./configure [OPTION]...

Defaults for the options (based on current environment) are specified in
brackets.

Configuration:
  -h, --help                 Print this help and exit
  --disable-fast-vapi        Disable the usage of Vala compilers fast-vapi
                             feature. fast-vapi mode is slower when doing
                             clean builds, but faster when doing incremental
                             builds (during development).
  --fetch-only               Only fetch the files required to run ./configure
                             without network access later and exit.
  --no-debug                 Build without debug symbols
  --release                  Configure to build an optimized release version
  --with-libsignal-in-tree   Build libsignal-protocol-c in tree and link it
                             statically.
  --with-tests               Also build tests.

Plugin configuration:
  --enable-plugin=PLUGIN     Enable compilation of plugin PLUGIN.
  --disable-plugin=PLUGIN    Disable compilation of plugin PLUGIN.

Installation directories:
  --prefix=PREFIX            Install architecture-independent files in PREFIX
                             [$PREFIX]
  --program-prefix=PREFIX    Same as --prefix
  --exec-prefix=             Install architecture-dependent files in EPREFIX
                             [PREFIX]
  --lib-suffix=SUFFIX        Append SUFFIX to the directory name for libraries

By default, \`make install' will install all the files in
\`/usr/local/bin', \`/usr/local/lib' etc.  You can specify
an installation prefix other than \`/usr/local' using \`--prefix',
for instance \`--prefix=\$HOME'.

For better control, use the options below.

Fine tuning of the installation directories:
  --bindir=DIR               user executables [EPREFIX/bin]
  --libdir=DIR               object code libraries [EPREFIX/lib]
  --includedir=DIR           C header files [PREFIX/include]
  --datadir=DIR              read-only data [PREFIX/share]

For compatibility with autotools, these options will be silently ignored:
--host, --build, --sbindir, --sysconfdir, --libexecdir, --sharedstatedir,
--localstatedir, --mandir, --infodir, --enable-dependency-tracking,
--disable-dependency-tracking

Some influential environment variables:
  CC                         C compiler command
  CFLAGS                     C compiler flags
  PKG_CONFIG_PATH            directories to add to pkg-config's search path
  PKG_CONFIG_LIBDIR          path overriding pkg-config's built-in search path
  USE_CCACHE                 decide to use ccache when compiling C objects
  VALAC                      Vala compiler command
  VALACFLAGS                 Vala compiler flags

Use these variables to override the choices made by \`configure' or to help
it to find libraries and programs with nonstandard names/locations.
