I am trying to run simple c++ application on Ubuntu 18.04 with using libconfig 1.7.2 library which was installed with vcpkg version 2018.11.23-unknownhash (Microsoft C++ Library Manager for Windows), cmake version is 3.14.3. Static library was linked well and include path specified but errors still exists. Can somebody helps me to find the problem?
