...instead of inconsitently having it depend on --enable-epm for some platforms and having it always enabled on Windows. Only Android and iOS are presumably still special and build any installation sets in their specific modules and outside instsetoo_native. One consequence is that for a non-Windows --enable-online-update --without-package-format build, instdir's version ini-file contains an UpdateURL that ends in just "?pkgfmt=" without an actual format identifier. However, checking whether the update feature would actually work is difficult for most such developer builds, anyway. Change-Id: If14fcf0b2e612499811e8a6e067a854bda612c42
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).
