Trying to build on Manjaro (Arch)

Hi. Awesome project.
I am trying to build on Manjaro (Arch) Linux. I have no problems compiling normal blender.

This is the repo i am trying to build: https://github.com/armory3d/blender_v8
I am assuming this is the 2.8 version?

However the build process fails with:

[ 98%] Generating buildinfo.h_fake, buildinfo.h
[ 98%] Built target buildinfo
[ 98%] Built target locales

[ 98%] Building C object source/creator/CMakeFiles/blender.dir/creator.c.o

make[2]: *** No rule to make target '/home/lubos/Downloads/blender-git/blender/source/blender/draw/engines/armory/V8/Libraries/linux/release/libv8.so', needed by 'bin/blender'.  Stop.
make[1]: *** [CMakeFiles/Makefile2:7492: source/creator/CMakeFiles/blender.dir/all] Error 2
make: *** [Makefile:163: all] Error 2

I am assuming that is because of these hardcoded paths in CMakeCache.txt ?

bf_draw_LIB_DEPENDS:STATIC=general;asound;general;dl;general;/home/lubos/Downloads/blender-git/blender/source/blender/draw/engines/armory/V8/Libraries/linux/release/libv8.so;general;/home/lubos/Downloads/blender-git/blender/source/blender/draw/engines/armory/V8/Libraries/linux/release/libv8_libbase.so;general;/home/lubos/Downloads/blender-git/blender/source/blender/draw/engines/armory/V8/Libraries/linux/release/libv8_libplatform.so;

Anyways some more explanation about the build proces would be appreciated.
Thanks for this awesome project.
