Shared builds are still very much a work-in-progress, roughly half[1] the 
packages haven’t had their shared builds enabled yet. Sometimes it’s a simple 
matter of replacing "build,host,prefix,[en|dis]able-[static|shared]" with 
"$(MXE_CONFIGURE_OPTS)” (e.g. src/expat.mk), but it really depends on the build 
system. exiv2 requires a workaround for libtool’s detection of shared libs:

https://github.com/mxe/mxe/commit/f4202755f56e4062d64fce3c731e0db4c2c695ff

which isn’t ideal and we don’t want to enable many more like that without some 
greater understanding and cleaner solutions. There are a few open tickets (375, 
393, 408) relating to shared builds, if you have some input on those or general 
knowledge about the intricacies of shared builds (declspec header macros, 
pkg-config files, libtool setup, linker options, autotools install locations 
...), it would be very helpful. Maybe a wiki page to consolidate all this 
before adding it to the docs?

Cheers,

Tony
