Perhaps you should add the directory containing `fontconfig.pc'
to the PKG_CONFIG_PATH environment variable

 * rpm: fontconfig-devel (Fedora, EPEL)

If fontconfig freetype2 is already installed, check that 'pkg-config' is in your
PATH and PKG_CONFIG_PATH contains a fontconfig freetype2.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=...'

You are missing a system dependency, install it from a terminal

sudo apt install libfontconfig1-dev
