I have CMake installed on my Ubuntu Linux. Trying to run CMake GUI in Linux. I found it works in Windows, but where to get it and how to run in Linux?
cmake is documented (type man cmake and see also cmake.org) as being a command, so it should not have any GUI interface:
DESCRIPTION
The "cmake" executable is the CMake command-line interface. It may be
used to configure projects in scripts. Project configuration settings
may be specified on the command line with the -D option.
And it is just generating a Makefile (to be used by the make command). I don't understand what kind of GUI are you expecting.
On Debian and derivatives like Ubuntu, you might install the cmake-gui or cmake-qt-gui package then run the cmake-gui command.
And make is often running GCC. Try make -p to understand the default rules of GNU make... So read documentation of GNU make and of GCC (and probably of GDB).
