CMake Error at /usr/lib/x86_64-linux-gnu/cmake/Boost-1.71.0/BoostConfig.cmake:117 (find_package): Could not find a package configuration file provided by "boost_filesystem" (requested version 1.71.0) with any of the following names: boost_filesystemConfig.cmake boost_filesystem-config.cmake Add the installation prefix of "boost_filesystem" to CMAKE_PREFIX_PATH or set "boost_filesystem_DIR" to a directory containing one of the above files. If "boost_filesystem" provides a separate development package or SDK, be sure it has been installed. Call Stack (most recent call first): /usr/lib/x86_64-linux-gnu/cmake/Boost-1.71.0/BoostConfig.cmake:182 (boost_find_component) /usr/share/cmake-3.16/Modules/FindBoost.cmake:443 (find_package) CMakeLists.txt:58 (find_package)
Solution:
The error message is trying to tell you that you don’t have the boost filesystem library installed (or CMake can’t find it).
On Ubuntu, for example, install it using
sudo apt -y install libboost-filesystem-dev
the same with "boost_iostreams"
