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.
