Auxiliary cmake-mode version format issue in Gentoo
melpa-stable provides packages for gentoo. Auxiliary/cmake-mode is versioned with "-3.15.0.-1.1" substring. This substring is incompatible with the gentoo package versionning scheme. Whereas cmake-mode-3.15.0alpha_p1 (alpha for -1 and _p1 for .1) is likely to fit. Cf Gentoo ebuild file format. Here's an indication on Gentoo forum that suggests replacing "-3.15.0.-1.1" with "-184.108.40.206.1" could suffice. My apologizes if post is out of scope or irrelevant here.
