MacOS 10.15.4

tried installing with brew:
Error: No available formula with the name "jwtpp"

tried building with Cmake:

cmake -Wno-dev -DCMAKE_TOOLCHAIN_FILE=/Users/xxxxx/Projects/vcpkg/scripts/buildsystems/vcpkg.cmake -DCMAKE_INSTALL_PREFIX=/usr/local/ ..

jsoncpp is built with vcpkg as described in jsoncpp repo. tried installing it with brew as well.

Thank you for reporting. brew formula is broken. I'll give a fix soon.
Regarding manual build, you have to install jsoncpp manually too.
brew install jsoncpp then try to build

Tap fixed. brew install jwtpp is working now

I tried "brew install jsoncpp" yesterday. It doesn't work as well. I suspect it needs some additional variable or something, like openssl needs OPENSSL_ROOT_DIR to compile, but it is not transparent which one and where. Anyway, brew install jwtpp works now, thank you very much!

FYI, I'm afraid brew package is missing include folder after installation.

[troian]

Yes. On MacOS you have to specify OPENSSL_ROOT_DIR on cmake stage.
For example -DOPENSSL_ROOT_DIR=$(brew --prefix openssl)

Thanks for reporting. There is a bug in CMakeLists.txt. Release v2.0.2 fixes it.
