Possible 2 bugs in Linux & vapoursynth

[Selur]

Argh,.. how I hate all those different build systems cmake/meson/...
No clue why but I can't get mesion to work properly.

ghdl VFR-maniac/L-SMASH-Works
ghdl l-smash/l-smash

./configure --prefix="$vsprefix" --extra-cflags="$CFLAGS" || cat config.log
make -j$JOBS lib
cp liblsmash.a ..

cd ../VapourSynth
./configure --prefix="$vsprefix" \
  --extra-cflags="-I../build $CFLAGS -Wno-deprecated-declarations" \
  --extra-ldflags="-L.. $LDFLAGS" \
|| cat config.log

make -j$JOBS
cp libvslsmashsource.so.1 ../libvslsmashsource.so

cd ..
finish libvslsmashsource.so

source: https://github.com/Selur/hybrid-vapoursy...hsource.sh
works fine and I thought changing it to:

ghdl HolyWu/L-SMASH-Works
ghdl l-smash/l-smash

./configure --prefix="$vsprefix" --extra-cflags="$CFLAGS" || cat config.log
make -j$JOBS lib
cp liblsmash.a ..

cd ../VapourSynth
CFLAGS="-I../build $CFLAGS -Wno-deprecated-declarations" LDFLAGS="-L.. $LDFLAGS" meson build --prefix="$vsprefix"

make -j$JOBS
cp libvslsmashsource.so.1 ../libvslsmashsource.so

cd ..
finish libvslsmashsource.so

would make it work with HolyWus build, but it aborts with:

Run-time dependency liblsmash found: NO (tried pkgconfig and cmake)

meson.build:41:0: ERROR: Dependency "liblsmash" not found, tried pkgconfig and cmake

and I can't get my head around why. :/ (my guess it I simply don't get how to set the linker flags properly for meson,..)

-> seeing that it's not the only plugins that fails (there's also eedi3m, mvtoolssf, nnedi3cl, tcanny), I'm more and more thinking about dropping Vapoursynth support completely on Linux, since I lack the time and motivation to maintain the Vapoursynth stuff,...

Cu Selur

Ps.: sorry, for the rant, just frustrated,.. (got tons of bugs to fix and not time)
