Facing issue in opening egui.

[subhajit26]

Hi,
I am getting error when I try to run this command <./riscvOVPsim.exe -variant RV32I -program /home/sbhuinya/imperas-riscv-tests/riscv-ovpsim/examples/dhrystone/dhrystone.RISCV32.elf -gdbegui>

The error is:
Error (DBC_IH) The environment variable IMPERAS_HOME is not set which suggests you do not have an installation that supports the graphical debugger
Error (OP_FIP) Failed to build platform 'riscvOVPsim'

I have installed the eguieclipse properly. I have java environment installed but still this does not work while the same command works with -gdbconsole.
Can You please help me to fix the issue.
