How can I list cmake default build option in command-line?
I need to build OpenCV libraries from source. Before that, I want to know what are the default build settings.

A list in cmake is a ; separated group of strings. To create a list the set command can be used. For example, set(var a b c d e) creates a list with a;b;c;d;e , and set(var "a b c d e") creates a string or a list with one item in it.
Editing CMakeLists Files These can be found in the Auxiliary directory of the source distribution, or downloaded from the CMake Download page.
Add a subdirectory to the build. Adds a subdirectory to the build. The source_dir specifies the directory in which the source CMakeLists.
cmake -LA
To list all option( and set( CACHE (cached) variables do:
mkdir build cd build cmake .. cmake -LA | awk '{if(f)print} /-- Cache values/{f=1}' Sample stdout:
AUTOGEMM_ARCHITECTURE:STRING=Hawaii BLAS_DEBUG_TOOLS:BOOL=OFF BLAS_DUMP_CLBLAS_KERNELS:BOOL=OFF BLAS_KEEP_KERNEL_SOURCES:BOOL=ON BLAS_PRINT_BUILD_ERRORS:BOOL=O The -A switch also show options marked as advanced, so you will likely want to omit it when casually browsing the most useful options.
You may also be interested in adding -H to show more help information about each option as previously mentioned at: https://stackoverflow.com/a/53075317/895245
cmake -LAH ccmake ncurses
sudo apt-get install cmake-curses-gui ccmake .. shows:
Tested in Ubuntu 16.10, cmake 3.5.2.

You can do cmake -LAH too. The H flag will provide you help for each option.
