Sure, I'm attaching the patch which I tried and seemed to work (at least for
installing `cmake@3.15.5` explicitly and using it).

Is it ok like this or shall I send it to guix-patches?

Cheers,

Subject: [PATCH] gnu: CMake: Add version 3.15.5.

Add CMake version 3.15.5 but do not replace the existing version to avoid
triggering the rebuild of all CMake-based packages.

See <https://issues.guix.gnu.org/issue/38060>.

* gnu/packages/cmake.scm (cmake-3.15.5): Add CMake 3.15.5.
