-- Could NOT find CURL (missing: HTTP) (found version "7.80.0")
-- Could NOT find CURL (missing: HTTP) (found version "7.80.0")

Try sudo apt install libcurl-dev since if you set CPR_USE_SYSTEM_CURL to ON it requires the curl header files on your system.

This one is not working but I did run sudo apt install libcurlpp-dev and it didn't help.

On a clean ubuntu:20.04 container for me all works as expected. You are installing the cpp bindings for libcurl. But we need the c bindings.

Here is how I did it:

git clone https://github.com/libcpr/cpr.git
cd cpr
mkdir build && cd build
apt install libssl-dev gcc g++ cmake git libcurl4-openssl-dev
cmake .. -DCPR_USE_SYSTEM_CURL=ON
cmake --build . --parallel
cmake --build . --target install

libcpr / cpr
