#Cmake vs make file difference install
Assuming everything worked and you're happy with the configuration, 'make' is a general command that searches for a file named 'Makefile' (this was generated when you called cmake) This step will compile OpenCV, and install the files onto your system. You'll notice that all those options can be set in CMakeLists.txt. At the end of a bunch of text, you'll see whether CMake failed or succeeded, and then if it succeeded, a summary of the various options you set. CMake project files (such as CMakeLists. Visual Studios native support for CMake enables you to edit, build, and debug CMake projects on Windows, the Windows Subsystem for Linux (WSL), and remote systems from the same instance of Visual Studio. This includes looking for libraries, checking your options, and setting various other settings. Its found at the top of the table of contents on this page. It'll look in the directory above build (the one with CMakeLists.txt), and start to generate build files.
If it isn't obvious, the first two commands make a build directory, because it's usually advised to keep build files separate from the main files. So how do you build? From the command line! (usually, I said earlier that there's CMakeGui, and that's an option as well, my quick example will be for a unix like command line) But it really just boils down to a few commands:įrom the root directory, the one with CMakeLists.txt: mkdir build Honestly, it's extremely unlikely that you'll be editing these files yourself, unless you're building a really customized version of OpenCV. Most of these are just general build options or scripts for finding some of the external/3rd party libs. What they do can be inferred from their file names. Most of configuration is as simple as that. Simply change "ON" to "OFF" to turn it off. Line 113 will let you decide if you want to include or omit IEEE1394 support. (CMake also has a GUI, so you may not even have to edit CMakeLists.txt directly!) The syntax might be overwhelming at first because of the absurd amount of options available, but if you take it slow and digest it, you'll see that it's pretty simple. If you scroll down to line 108, you'll see where you can edit some build options. Open it up and try to read the comments, because OpenCV guys put a pretty decent amount of comments in there and despite it's size, it's decently organized for a CMakeLists.txt file. When you invoke CMake, the first thing it does is look for this file.
txt file you'll be interested in is "CMakeLists.txt." This is the main configuration file for CMake that it uses when building your project.
To answer your question directly, the main.
#Cmake vs make file difference how to
That said, I'll give you a quick summary of how to use it. I will admit that CMake is pretty difficult to comprehend a lot of the times, but when set up properly it can be pretty damn cool. But seriously, tutorials are out there for reading.
