Probably is not a bad idea to add prefix to the options. I.e. INTEL_PCM_.
After this, the options will be named not like NO_ASAN, but like INTEL_PCM_NO_ASAN.
Why:
Visually "highlight" PCM options.
Remove potential intersection with other projects. I.e., somebody using add_subdirectory and has an option with a name similar to PCM. He doesn't want to affect the PCM option, but he does and needs to make workarounds.
Remove potential intersection with special CMake variables.
How:
Add new options with prefixes.
Add stub for old option names, which will print deprecation warning.
Remove old names in some future version.
P.S.: Probably CMake option command will be more natural and convenient to use than "ordinary variables".
