-C <initial-cache>
       Pre-load a script to populate the cache.

       When cmake is first run in an empty build tree, it creates a CMakeCache.txt file and populates  it
       with  customizable settings for the project.  This option may be used to specify a file from which
       to load cache entries before the first pass through the project's  cmake  listfiles.   The  loaded
       entries  take priority over the project's default values.  The given file should be a CMake script
       containing SET commands that use the CACHE option, not a cache-format file.

-D <var>:<type>=<value>
       Create a cmake cache entry.

       When cmake is first run in an empty build tree, it creates a CMakeCache.txt file and populates  it
       with  customizable  settings  for  the project.  This option may be used to specify a setting that
       takes priority over the project's default value.  The option may be repeated  for  as  many  cache
       entries as desired.

-U <globbing_expr>
       Remove matching entries from CMake cache.

       This  option  may  be  used to remove one or more variables from the CMakeCache.txt file, globbing
       expressions using * and ? are supported. The option may be repeated for as many cache  entries  as
       desired.

       Use with care, you can make your CMakeCache.txt non-working.

-G <generator-name>
       Specify a makefile generator.

       CMake  may  support  multiple  native build systems on certain platforms.  A makefile generator is
       responsible for generating a particular build system.  Possible generator names are  specified  in
       the Generators section.

-Wno-dev
       Suppress developer warnings.

       Suppress warnings that are meant for the author of the CMakeLists.txt files.

-Wdev  Enable developer warnings.

       Enable warnings that are meant for the author of the CMakeLists.txt files.

       specified, the help is written into it.

--help-html [file]
