dependency ‘Cairo’ is not available for package ‘ComplexHeatmap’ on Ubuntu 20.04 LTS

Please what could be a reason for this error? I am trying to install the R package ComplexHeatmap but I keep getting the error message that the the dependency Cairo is not available. I have tried to install Cairo using the command sudo apt-get install libcairo2-dev but I still get the same error. Running the command sudo dpkg-query -l | grep libcairo2-dev also shows that the Cairo package is fully installed.

Below are the commands I have run and the respective outputs:

Installation of ComplexHeatmap

compilation terminated.

Thanks in advance for any help.

You are probably do not want to read the messages which are shown during compilation. The Cairo package also requires X11/Intrinsic.h from libxt-dev package.

For Ubuntu 20.04 LTS with R 4.1 use commands below to install needed build-dependencies:

sudo apt-get install libcairo2-dev libxt-dev

and then retry.
