try

"-lglslang -lMachineIndependent -lOSDependent -lHLSL -lOGLCompiler
-lGenericCodeGen \
                                                        -lSPVRemapper
-lSPIRV -lSPIRV-Tools-opt -lSPIRV-Tools -lpthread -lstdc++ -lm"

as you additional libs in

export EXTRA_LIBS= line before you run configure ...


fished out of ffmpeg's configure script by using less and search function
for 'glslang' word in it .... "/" and ten "n" few times ...


this amount of libs, even if they all just sub- components makes me sad.
