Error: Error installing package 'protolite':

[benjcowley]

Hi, seem to have an issue when trying to build using renv, I've had a google around but the only fixes I've seen seem to apply to fixing this on a local machine rather than with this build pack. Any ideas how to go about fixing this?

Error: Error installing package 'protolite':
=====================================

   * installing *source* package ‘protolite’ ...
   ** package ‘protolite’ successfully unpacked and MD5 sums checked
   ** using staged installation
   Package protobuf was not found in the pkg-config search path.
   Perhaps you should add the directory containing `protobuf.pc'
   to the PKG_CONFIG_PATH environment variable
   No package 'protobuf' found
   Using PKG_CFLAGS=
   Using PKG_LIBS=-lprotobuf
   Found C++17 compiler: g++ -std=gnu++17 -g -O2
   ------------------------------[ ANTICONF ]-----------------------------
   Configuration failed to find protobuf. Try installing:
    * deb: libprotobuf-dev (Debian, Ubuntu, etc)
    * rpm: protobuf-devel (Fedora, EPEL)
    * brew: protobuf (OSX)
   If protobuf is already installed, check that 'pkg-config' is in your
   PATH and PKG_CONFIG_PATH contains a protobuf.pc file. If pkg-config
   is unavailable you can set INCLUDE_DIR and LIB_DIR manually via:
   R CMD INSTALL --configure-vars='INCLUDE_DIR=... LIB_DIR=...'
