Question

I can’t seem to find much about this, so maybe it isn’t possible… or I am searching with the wrong keywords.

Anyway, I have a directory of source. Let’s say that there is a folder within Source called Tests and another called Products. I have the usual hierarchy of CMakeLists.txt files so that I can build all the source in each directory and subdirectory, etc… What I want to know is if it is possible to pass a command line argument with cmake so that it will only build the tests folder or the source folder.

e.g. something like cmake TEST ..

Thanks

Of course you can use flags.

if(TEST)
 include needed folders
else()
 do something else
endif()

And call cmake like this:

cmake -DTEST=1 ..
