Case sensitivity GSL_DIR=BUILD

[Christian Reisswig]

The thorn GSL would not compile if "GSL_DIR=build" in the option list. In order to work, it requires "GSL_DIR=BUILD", i.e. it is really case sensitive although I think, this is not required and should be case insensitive.

Possibly, HDF5_DIR=build may also not work for the same reason (have not checked; should be checked as well).

build3.patch works; ignore the previous two.

(The patch addresses the problem for many thorns in ExternalLibraries other than HDF5, and additionally tidies up some formatting.)

This looks good - please apply.

[Frank Löffler]

Looks good (but please don't mix up changes in patches which are not related to the issue. The changes are all fine, but make reviewing more complicated). Please apply.

Was this patch applied?

Yes.
