CMake Error at CMakeLists.txt:10 (FIND_PACKAGE):
  Could not find a package configuration file provided by "LIBMINC" with any
  of the following names:

    LIBMINCConfig.cmake
    libminc-config.cmake

  Add the installation prefix of "LIBMINC" to CMAKE_PREFIX_PATH or set
  "LIBMINC_DIR" to a directory containing one of the above files.  If
  "LIBMINC" provides a separate development package or SDK, be sure it has
  been installed.
