Remove FindSDL2 find-module, use sdl2-config.cmake instead
This requires SDL >= 2.0.4.
Since <https://bugzilla.libsdl.org/show_bug.cgi?id=2464> was fixed in
SDL 2.0.4, SDL behaves as a CMake "config-file package", even if it was
not itself built using CMake: it installs a sdl2-config.cmake file to
${libdir}/cmake/SDL2, which tells CMake where to find SDL's headers and
library, analogous to a pkg-config .pc file.
As a result, we no longer need to copy/paste a "find-module package"
to be able to find a system copy of SDL >= 2.0.4 with find_package(SDL2).
Find-module packages are now discouraged by the CMake developers, in
favour of having upstream projects behave as config-file packages.
This results in a small API change: FindSDL2 used to set SDL2_INCLUDE_DIR
and SDL2_LIBRARY, but the standard behaviour for config-file packages is
to set <name>_INCLUDE_DIRS and <name>_LIBRARIES. Use the CONFIG keyword
to make sure we search in config-file package mode, and will not find a
FindSDL2.cmake in some other directory that implements the old interface.
In addition to deleting redundant code, this avoids some assumptions in
FindSDL2 about the layout of a SDL installation. The current libsdl2-dev
package in Debian breaks those assumptions; this is considered a bug
and will hopefully be fixed soon, but it illustrates how fragile these
assumptions can be. We can be more robust against different installation
layouts by relying on SDL's own CMake integration.
When linking to a copy of CMake in a non-standard location, users can
now set the SDL2_DIR or CMAKE_PREFIX_PATH environment variable to point
to it; previously, these users would have used the SDL2DIR environment
variable. This continues to be unnecessary if using matching system-wide
installations of CMake and SDL2, for example both from Debian.
Hedgewars - a turn-based strategy game
======================================
[](https://travis-ci.org/hedgewars/hw)
Description
-----------
This is the funniest and most addictive game you'll ever play—hilarious fun
that you can enjoy anywhere, anytime. **Hedgewars** is a **turn-based strategy
game** but the real buzz is from watching the **devastation caused by those
pesky hedgehogs** with those fantastic weapons—sneaky little blighters with
a bad attitude!
Each player controls a **team of up to 8 hedgehogs**. During the course of
the game, players take turns with one of their hedgehogs. They then use
whatever tools and weapons are available to **attack and kill the opponents'
hedgehogs**, thereby winning the game.
To destroy your foes you can use one out of **over 40 weapons**!
Launch bazookas or homing bees, drop mines, dynamite or explosive rubber ducks,
throw grenades or watermelon bombs, poison them with stinky cheese, send them
flying with a baseball bat, and much more!
Most weapons cause **explosions that deform the terrain**, removing
circular chunks. Hedgehogs can die by drowning, being thrown off
either side of the arena, or when their health is reduced to zero.
Hedgehogs may move around the terrain in a variety of ways, normally by
walking and jumping but also by using particular tools such as the rope
or parachute, to move to otherwise inaccessible areas. Each **turn is
time-limited** to ensure that players do not hold up the game with
excessive thinking or moving.
Getting started
---------------
For complete beginners we recommend to play in singleplayer mode first.
Start with the Basic Movement Training found in the training menu.
Proceed with the other training missions.
After completing the training, try to play some quick matches against the
computer (also found in the singleplayer menu).
Hedgewars has many weapons, so play a few matches to get a better feeling
for them.
