Subject: subprojects: Allow expat and GLib to be built as subprojects
X-Git-Tag: dbus-1.15.0~32^2~67
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=4fbdb149878431e71efed1977508d00d7d77376e;p=thirdparty%2Fdbus.git

subprojects: Allow expat and GLib to be built as subprojects

This should let us build everything with a mingw-w64 toolchain, without
having to use prebuilt dependencies from MSYS.
