One way this could be done without breaking things might be to create a
subdirectory of /usr/$(get_libdir) for each version of Lua and creating
a liblua.a and/or liblua.so symlink in that directory pointing to the
liblua${VERSION}.* file in /usr/$(get_libdir). Then you could simply
point those build systems at that directory and they would still use the
correct version. As a hack in an ebuild, you probably could just create
such a setup in (subdirectories of) ${T}, pointing liblua.a, liblua.so,
and lua.pc at the appropriately-versioned files.
All of these packages are masked, so breakage isn't an issue.
And since these hacks are needed in every package that will link against
liblua, doesn't it sound like something the eclass should be doing? Even
the CMake packages would benefit, no longer having to pass in
-DLUA_INCLUDE_DIR and -DLUA_LIBRARY by hand.
