Currently if in source builds are set to true, %cmake_install appends a "." current directory.

I'm working on building Avidemux on RPM Fusion and it requires multiple cmake builds and fakeroot installs which means I have to allow "in source builds" to stop the new behavior even though I'm manually performing multiple out-of-source builds.

During %install I would much prefer to do something likes:
%cmake_install <dir1>
%cmake_install <dir2>
%cmake_install <dir3>...

But that's currently not possible because it assumes "." is appropriate. I'd really rather not have to pushd into each directory as that's just ugly :)

Is there a way to modify the behavior of the macro to not append "."?

Thanks,
Richard
