Fix engine build when png lib isn't available

uscript rendering

Silly me

little cleanup after so many merges

added campaign descriptions in CMakeList

really update with default

issue #672, frontend less spammy

This commit changes many aspect of our cmake build system - shared libraries are compiled by default: * this modifies RPATH of unix executables; * this will prevent a lot of linking issues, esp. from pascal world; * the old behaviour (static libs) is still available with -DBUILD_SHARED_LIBS=off; * of course in this case you have to provide the full list of dependencies with FPFLAGS and CMAKE_C_FLAGS; - pascal is now fully integrated with cmake, meaning you can just do add_sources and use CMAKE_Pascal_FLAGS: * some of the language features are only partially implemented, for example .inc files will not get rebuilt if you modify them; * target_link_libraries for pascal targets is just dummy as linking is determined within pascal files; * universal builds for osx are not available any more; - bundled libraries and system libraries are addressed using the target name: * this avoids depedency tracking; * this allows to name output as we wish.

when you don't use bundled dirs, add a fake target anyway, so you can use the same cmake syntax even if the target uses a different name

there is no need of escaping after all...

this should fix rpath problem

oops, forgot to set the path after all

less spam

remove two unused cmake files

this should resolve a few issues on clean builds

oops, use right macro name

use target name instead of the resulting library, use more macros around

merge cmake_pascal branch in default

actually tests are there to be tested, just skip the variable assignment on windows

Backed out changeset c4289023ddae

don't run the broken windows test at all on windows

gather up the linker flags in a macro

bring windows fixes from main repo

another code typo

apply linker flags to all relevant targets

explicitly set the origin linker flag so that $ORIGIN is used correctly

add a possible lua include path

less cached cmake output

code typos

use QT_DEBUG which is always added

respect C and CXX flags

freepascal on windows only supports shared libraries

nitpick

heavily rework lua discovery and linking, needs testing but it's more similar to what we do for other libraries now

oops, haskell uses gcc to link, correctly pass flags

since shared libs are now our friends, let's optimise them

aaaaand let's not forget about lua, which has also a slightly revised build process

drop the '_'

and now also avwrapper can be shared/static, add visibility to its exported functions, drop (needed only when static)

also physlayer can be comiled as static or shared now

redid FindGLEW in the right way (tm)

love cmake when it works

pas2c import

setup RPATH, bump cmake

update with default

these check are now useless

Many of the gears treat non-0 timer as overridden. Added that check in more places so that lua could use this a tiny bit more consistently. Also preserve state for jetpack.

I hate you, I hate you with all my heart...

'i' flag for in-room status

use BUILD_SHARED_LIBS to control whether a library is shared or static, make our bundled physfs library check for this configuration

fix launching on windows

move paths setup in separate cmake module

merge my campaign page changes with default

backout r1bed4aee19e0 and r3883b5dc600c

moar cpack ignore

merge (could have grafted)

osx, link also foundation to physfs

added images and corrected bug that didn't show correct description at some occasions

libssp (required by stack-protector) is not available on 10.4

issue #562, image and description for the campaign page
