Comment:
cantata-replaygain and cantata-tags don't have to be installed alongside the main executable. I believe setting this parameter this way will lead to a folder being created under /usr/bin which is probably not wanted.

I'm not familiar with Void's semantics on the use of libexec, but CMake suggests that LIBEXECDIR be relative (it is then relative to CMAKE_INSTALL_PREFIX.) It is probably best to leave it as default (`libexec`) or if needed, `lib64/libexec` (wherever the libexec dir is relative to /usr, the CMAKE_INSTALL_PREFIX.) Then these features will work properly.
