Unwanted double-caching when ccache is also installed

[avikivity]

If ccache is installed and has /usr/lib64/ccache in $PATH, then sccache gcc ... will actually call /usr/lib64/ccache/gcc, which is in fact ccache, resulting in double-caching.

It would be easier for users migrating from ccache (or having some projects using ccache and some projects using sccache) if sccache automatically set the CCACHE_DISABLE environment variable before invoking the compiler.

Isn't it possible in this case to just chain sccache ccache?

The goal is to avoid double-caching, which is usually unwanted.
