Grigori Fursin converted the original sconscript from the ARM Compute Library into the CK format in order to add ARMCL to CK auto/crowd-tuning workflows.
To install the package from a separate branch (other than master), use the following command:
$ ck install package:lib-armcl-opencl-master
You can also install a specific sub-branch as follows: $ ck install package:lib-armcl-opencl-master (--env.PACKAGE_GIT_CHECKOUT=your_branch --extra_version=-your_branch)
This will create a new env entry without conflicting with the already installed master entry.
