Not able to build on RHEL 7.9 using make or cmake

[singhpranjul]

Hello Team,

I am not able to build llama.cpp on my RHEL Setup. There might be a silly error in my environment.
I have updated the GCC compiler to 3.9 also but still facing the below error:

[install@ps-portfolio-seabed llama.cpp]$ make
which: no ccache in (/usr/local/bin:/usr/local/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/home/install/.local/bin:/home/install/bin)
I ccache not found. Consider installing it for faster compilation.
I llama.cpp build info:
