minc provides CMake integration:

  find_package(LIBMINC CONFIG REQUIRED)
  target_include_directories(main PRIVATE ${LIBMINC_INCLUDE_DIRS})
  target_link_directories(main PRIVATE ${LIBMINC_LIBRARY_DIRS})
  target_link_libraries(main PRIVATE ${LIBMINC_LIBRARIES})

LIBMINC_LIBRARIES may include imported targets.
Downstream CMake config may need to add:

  include(CMakeFindDependencyMacro)
  find_dependency(LIBMINC CONFIG)
