Subject: build: Improve detection av Ccache version from source repo
X-Git-Tag: v4.4~1
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=2652a1777c3781d4b00330538b17363943f844f7;p=thirdparty%2Fccache.git

build: Improve detection av Ccache version from source repo

When running CMake outside the source repository a plain git command
naturally won’t find the repository. Fix this by pointing git towards
the repository.
