Configuration failed to find libgit2 library – CentOS

When attempting to install the R devtoolspackage (on Linux Mint, 19.3 & R 4.0.2),I receive this error. In the ANTICONF section the message offers some suggestions for what I should do, but being new to Linux I don’t understand how to implement the instructions, and my search of the internet has not yielded fruit. Could someone offer guidance on the commands/steps I need to take to install libgit2 or resolve this issue?

Configuration failed to find libgit2 library. Try installing:
* brew: libgit2 (MacOS)
* deb: libgit2-dev (Debian, Ubuntu, etc)
* rpm: libgit2-devel (Fedora, CentOS, RHEL)
If libgit2 is already installed, check that 'pkg-config' is in your
PATH and PKG_CONFIG_PATH contains a libgit2.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=...'
