Hi, 

As i mentioned i have jenkins on Ubuntu 18.04 and I am able to configure jobs for C, Qt aplications(Desktop) and works fine with this requirement but when i want create jobs to build Qt WebAssembly, make fails due to some absulute path issues for more info please refer below summary

WARNING root: -I or -L of an absolute path "-I/home/kmb/Qt/5.14.0/wasm_32/include" encountered. If this is to a local system header/library, it may cause problems (local system files make sense for compiling natively on your system, but not necessarily to JavaScript). Pass '-Wno-warn-absolute-paths' to emcc to hide this warning.
WARNING root: Disabling asm.js validation for memory growth (memory can grow, but you lose some amount of speed)
