sys-process/btop-1.2.13-r2 fails to emerge in the install phase if ccache is enabled with the following messages: ######## ccache: error: Could not find compiler "g++-12" in PATH Makefile:78: *** ERROR: Compiler too old. (Requires Clang 16.0.0, GCC 10.1.0). Stop. ######## Reproducible: Always Steps to Reproduce: 1. Configure /etc/portage/make.conf 2. Run emerge -v btop Actual Results: Merge fails in the install phase with the message seen above. Expected Results: The merge should be completed successfully just like it is without ccache. The problem can be worked around by temporarily disabling ccache.

Alright, so btop doesn't respect CXX unless it is explicitly fed to in the make invocation. As its fed to the compile phase but not in the install phase leading to this failure later. Not sure why the non-existent g++-12 in particular was chosen other than the makefile conditional omitting g++-13 completely. The clear solution is to feed CXX in install phase similar to the compile phase.
I've noticed that btop also has a CMake build system now. I plan on switching to the CMake build system for future versions as it simplifies the ebuild. This should also fix this issue.
