Build specific modules OpenCV

Question

I\'d like to ask how can I specify OpenCV modules to build by cmake ex. I\'d like to build only core, highgui and improc.

Thank you for your responses because I goog

Answer 1

you can toggle each module by specifying it to cmake:

-DBUILD_opencv_xxxx=OFF # where xxxx is the module in question, and ON or OFF is your requested state

with cmake

Answer 2

In the CMakeCache.txt file there is an option BUILD_LIST. You can edit that file directly or specify it on the command line

CMakeCache.txt, relevant line

//Build only listed modules (comma-separated, e.g. 'videoio,dnn,ts') BUILD_LIST:STRING=

Command line

cmake -DBUILD_LIST=core,highgui,improc ..

Answer 3

you can use Cmake GUI to see what you are building just point Cmake GUI to the directory of opencv source code. then you choose the compiler version you would like to compile with.

Once generation is done. you have a very nice UI representation of what you would like to build.
