So actually, --with-foo-dir is usually for build, not install (i.e.
what directory is foo located in). Not sure what the standard is for
"install to random other directory is" with autoconf, but how about
With the appropriate information in the configure help, and error out
if both are specified. Does that make everyone happy?
It should be noted that the contents of the icd file aren't
particularly groundbreaking -- just a text file with
"libMesaOpenCL.so" in it -- so even if you have one from your system
install, and stick mesa elsewhere and its icd file goes to that other
"wrong" location, you will still have a mesa icd file there, and
things will work (provided you supply a LD_LIBRARY_PATH).
