I extracted the file to home/tom/warzone2100-2.2.1 and configured in this folder (home/tom/warzone2100-2.2.1/configure). Then appear a notice like this:
...
checking for pkg-config... /usr/bin/pkg-config
checking pkg-config is at least version 0.9.0... yes
checking for pkg-config >= 0.9... found 0.22, ok
checking whether to build NSIS installer... no
checking whether to compile in debug mode... no
checking for SDL... configure: error: Package requirements (sdl >= 1.2) were not met:
No package 'sdl' found
Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.
Alternatively, you may set the environment variables SDL_CFLAGS
and SDL_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.
Tell me what I have to do next. Then how can I install
