The package inih provides unofficial CMake targets:
    find_package(unofficial-inih CONFIG REQUIRED)
    # C API
    target_link_libraries(main PRIVATE unofficial::inih::libinih)
    # C++ API (Requires "cpp" feature)
    target_link_libraries(main PRIVATE unofficial::inih::inireader)
Alternatively, if you are using pkg-config use the name "inih" for the C API and "inireader" for the C++ API
