Update feature

[marek2001]

Pre-submit checks

• I checked for similar issues beforehand, but could not find any, not even closed ones. I could not add my bug report to any existing issue.
• I am going to take the time to to fill in all the required details. I know that the bug report will be dismissed otherwise.

Describe the bug

-DENABLE_UPDATE_HELPER=ON \ to cmake

But even after ignoring some "compile warnings treated as errors", it still won't build (error in "build/_deps/cpr-src/cpr/").

Is update feature implemented already?

Expected behavior

Update feature show green checkmark in appimage launcher settings.

Steps to reproduce the issue

export PREFIX="/usr/local/"
mkdir build
cd build

cmake .. -DCMAKE_INSTALL_PREFIX="$PREFIX" -DUSE_SYSTEM_BOOST=true -DENABLE_UPDATE_HELPER=ON

See #251 for more details why this is required

make libappimage libappimageupdate libappimageupdate-qt
cmake .

make

Found this thread when searching for a similar problem. I'm trying to compile based off the AUR package, which downloads the upstream release from this repo. Have the same -DENABLE_UPDATE_HELPER=ON added to cmake. This is the error output I'm getting:

When -DENABLE_UPDATE_HELPER=ON is removed, it compiles just fine with no issue.
