-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.

-E     CMake command mode.

       For true platform independence, CMake provides a list of commands that can be used on all systems.
       Run with -E help for the usage information. Commands available are:  chdir,  compare_files,  copy,
       copy_directory, copy_if_different, echo, echo_append, environment, make_directory, md5sum, remove,
       remove_directory, rename, tar, time, touch, touch_nocreate. In addition,  some  platform  specific
       commands are available. On Windows: comspec, delete_regv, write_regv. On UNIX: create_symlink.

-i     Run in wizard mode.

       Wizard  mode  runs  cmake  interactively  without a GUI.  The user is prompted to answer questions
       about the project configuration.  The answers are used to set cmake cache values.

--build <dir>
       Build a CMake-generated project binary tree.

       This abstracts a native build tool's command-line interface with the following options:

-P <file>
       Process script mode.

       Process the given cmake file as a script written in the CMake language.  No configure or  generate
       step  is  performed and the cache is not modified. If variables are defined using -D, this must be
       done before the -P argument.

--find-package
       Run in pkg-config like mode.

       Search a package using find_package() and print the resulting flags to stdout. This can be used to
       use cmake instead of pkg-config to find installed libraries in plain Makefile-based projects or in
       autoconf-based projects (via share/aclocal/cmake.m4).

--graphviz=[file]
       Generate graphviz of dependencies.

       Generate a graphviz input file that will contain all the library and  executable  dependencies  in
       the project.

--system-information [file]
       Dump information about this system.

       Dump  a  wide  range of information about the current system. If run from the top of a binary tree
       for a CMake project it will dump additional information such as the cache, log files etc.

--debug-trycompile
       Do not delete the try_compile build tree. Only useful on one try_compile at a time.

       Do not delete the files and directories created for try_compile calls. This is useful in debugging
       failed  try_compiles.  It  may  however  change the results of the try-compiles as old junk from a
       previous try-compile may cause a different test to either pass or fail incorrectly.   This  option
       is best used for one try-compile at a time, and only when debugging.

--debug-output
       Put cmake in a debug mode.

       Print extra stuff during the cmake run like stack traces with message(send_error ) calls.

--trace
       Put cmake in trace mode.

       Print a trace of all calls made and from where with message(send_error ) calls.

--warn-uninitialized
       Warn about uninitialized values.

       Print a warning when an uninitialized variable is used.

--warn-unused-vars
       Warn about unused variables.

       Find variables that are declared or set, but not used.

--no-warn-unused-cli
       Don't warn about command line options.

       Don't find variables that are declared on the command line, but not used.

--check-system-vars
       Find problems with variable usage in system files.

       Normally,  unused  and  uninitialized  variables  are  searched  for  only in CMAKE_SOURCE_DIR and
       CMAKE_BINARY_DIR. This flag tells CMake to warn about other files as well.
