solver means "Solar Version", a weird name with only historical significance now It has no relation to the verb "to solve". solver is the directory tree into which header files for inter-module use and build results (libraries, shared libraries, executables) are copied ("delivered") during the build, and from where they are then picked up when constructing an installer (Windows), a RPM or deb package (Linux) or an app bundle (Mac).
