The minimum required cmake version is raised to 3.1, because the exported targets started at that version. The build system creates the exported targets: - The executable uchardet::uchardet - The library uchardet::libuchardet - The static library uchardet::libuchardet_static A downstream project using CMake can find and link the library target directly with cmake (without needing pkg-config) this way: ~~~ project(sample LANGUAGES C) find_package ( uchardet ) if (uchardet_FOUND) add_executable( sample sample.c ) target_link_libraries ( sample PRIVATE uchardet::libuchardet ) endif () ~~~ After installing uchardet in a prefix like "$HOME/uchardet/": cmake -DCMAKE_PREFIX_PATH="$HOME/uchardet/;..." Instead installing, the build directory can be used directly, for instance: cmake -Duchardet_DIR="$HOME/uchardet-0.1.0/build/" ...
