Prerequisites {#gtk_prereq}
-------------
To build wxWidgets, you need to have a number of libraries on your system.
While all of them may be compiled from source, under Linux systems it is much
more common to install the development packages containing the headers and
library files.
At the very least, you will need GTK libraries themselves. Unfortunately the
exact package names differ between different Linux distributions, but for
Debian and Debian-based distribution these libraries are part of `libgtk-3-dev`
package, while in Fedora and other RPM-based distributions the same package is
known as `gtk3-devel`.
For OpenGL support, you need `libgl1-mesa-dev` and `libglu1-mesa-dev` packages
under Debian and `mesa-libGL-devel` and `mesa-libGLU-devel` under Fedora. For
EGL support, `libegl1-mesa-dev` or `mesa-libEGL-devel` is needed.
wxMediaCtrl implementation requires GStreamer and its plugins development
packages, i.e. either `libgstreamer-plugins-baseVERSION-dev` or
`gstreamerVERSION-plugins-base-devel`, where `VERSION` should be 1.0, but 0.10
is still supported as well for compatibility with old systems.
wxWebRequest requites libcurl development package, e.g. `libcurl4-openssl-dev`
or `libcurl-devel`.
wxWebView requires `libwebkit2gtk-4.0-dev` under Debian and `webkit2gtk3-devel`
under Fedora.
For the different image format libraries (PNG, JPEG, TIFF) as well as zlib, you
may install the corresponding `libNAME-dev` or `-devel` libraries or use the
built-in versions of them, i.e. the same libraries compiled as part of
wxWidgets, instead if you prefer.

minimize external dependencies. By default, system versions will be
used if available, but `--with-xxx=builtin` configure option may be
used to override this.
--disable-sys-libs Don't use system libraries when there is

This is equivalent to using --with-xxx=builtin

Note that other system libraries can,
and typically will, still be used if
found.
