Identical to "./configure --help", when a project uses cmake, we get building instructions like below,
1 2 3 4 | mkdir bld cd bld cmake .. cmake . -L |
wait a while we will see all the variables cmake defined in cache.
Or directly look into CMakeCache.txt.
If we want to modify a variable to off, or say, disable some functionality,
1 | FEATURE_test_name:BOOL=ON |
we run cmake once again like this,
1 | cmake -DFEATURE_test_name:BOOL=OFF .. |
