I wonder if this could be addressed by discarding the desire to
run magically "out of the box", but make the requirements
Currently the choices seem to be:
* Require the user to install these libs+headers
"just right" (on the PATH or in certain MSYS
directories) so that they are found.
* Edit the cabal package file to point to the
Perhaps a worthwhile addition to cabal would be for it to be able to
read a local config file, in which a user would specify where each
package should get the necessary headers and libs? You'd manually create
this file, maybe like:
When building a package X, cabal would consult this file to work out
localised options for that package.
