+Subject: [PATCH] OptionsGTK.cmake: drop the hardcoded introspection/gtkdoc
+ disabling when cross-compiling
+
+This was not possible to override from the command line and in OpenEmbedded
+(one of the most prominent cross-compilation frameworks) introspection does work fine,
+through the use of qemu target emulation.

+
+g-ir-compiler is using a C compiler internally, so it needs to set
