Ubuntu 18.04.3 LTS - building ktx failed

I use Ubuntu 18.04.3 LTS (gcc 7.4.0) I have successfully built shaderc with all components required by ktx library. When I build ktx library (cmake/Iinux/debug or release) I get following errors:

[ 91%] Linking CXX executable gl3loadtests
/usr/bin/ld:/home/user/Downloads/KTX-Software-master/build/cmake/linux/Release/../../../../other_lib/linux/Release-x64/libSDL2-2.0.so: file format not recognized; treating as linker script

Has anybody gotten the same errors on the linux ? How to fix that ?

This is because Git LFS was either not installed or not initialized when you checked out the repo.

If you had filed an issue at GitHub - KhronosGroup/KTX-Software: KTX (Khronos Texture) Library and Tools you would have got a faster response.
