"CMake is used to configure and generate build files for software projects. "
"The basic steps for configuring a project with ccmake are as follows:\n\n"
"1. Run ccmake in the directory where you want the object and executable "
"files to be placed (build directory). If the source directory is not the "
"same as this build directory, you have to specify it as an argument on the "
"command line.\n\n"
"2. When ccmake is run, it will read the configuration files and display "
"the current build options. "
"If you have run CMake before and have updated the configuration files "
"since then, any new entries will be displayed on top and will be marked "
"with a *. "
"On the other hand, the first time you run ccmake, all build options will "
"be new and will be marked as such. "
"At this point, you can modify any options (see keys below) you want to "
"change. "
"When you are satisfied with your changes, press 'c' to have CMake process "
"the configuration files. "
"Please note that changing some options may cause new ones to appear. These "
"will be shown on top and will be marked with *. "
"Repeat this procedure until you are satisfied with all the options and "
"there are no new entries. "
"At this point, a new command will appear: G)enerate and Exit. You can now "
"hit 'g' to have CMake generate all the build files (i.e. makefiles or "
"project files) and exit. "
"At any point during the process, you can exit ccmake with 'q'. However, "
"this will not generate/change any build files.\n\n"
"ccmake KEYS:\n\n"
"Navigation: "
"You can use the arrow keys and page up, down to navigate the options. "
"Alternatively, you can use the following keys: \n"
" C-n : next option\n"
" C-p : previous options\n"
" C-d : down one page\n"
" C-u : up one page\n\n"
"Editing options: "
"To change an option press enter or return. If the current options is a "
"boolean, this will toggle it's value. "
"Otherwise, ccmake will enter edit mode. In this mode you can edit an "
"option using arrow keys and backspace. Alternatively, you can use the "
"following keys:\n"
" C-b : back one character\n"
" C-f : forward one character\n"
" C-a : go to the beginning of the field\n"
" C-e : go to the end of the field\n"
" C-d : delete previous character\n"
" C-k : kill the rest of the field\n"
" Esc : Restore field (discard last changes)\n"
" Enter : Leave edit mode\n"
"You can also delete an option by pressing 'd'\n\n"
"Commands:\n"
" q : quit ccmake without generating build files\n"
" h : help, shows this screen\n"
" c : process the configuration files with the current options\n"
" g : generate build files and exit, only available when there are no "
"new options and no errors have been detected during last configuration.\n"
" l : shows last errors\n"
" t : toggles advanced mode. In normal mode, only the most important "
"options are shown. In advanced mode, all options are shown. We recommend "
"using normal mode unless you are an expert.\n"
" / : search for a variable name.\n";
