try to build latest libevent source:

cmake -H. -Bbuild -DCMAKE_INSTALL_PREFIX=$(pwd)/install -DCMAKE_BUILD_TYPE=Debug -DEVENT__DISABLE_OPENSSL=ON -DEVENT__DISABLE_MBEDTLS=OFF -~E_BENCHMARK=ON -DEVENT__DISABLE_SAMPLES=ON -DEVENT__DISABLE_TESTS=ON  -DEVENT__DISABLE_MBEDTLS=ON -DCMAKE_INSTALL_RPATH=$(pwd)/install/lib

get the same error.

cmake version issue:

ubuntu 20.04 - (from packages) v3.16.x - not ok
ubuntu 21.10 - (from packages) v3.18.x - not ok
ubuntu 20.04 - (from source) v3.24.x - ok

Opened issue in libevent repo. As for temporary workaround pip install cmake will mitigate issue on local build machine

upgrading cmake from sources to version 3.24.0 has worked for me.
