When subdir is '/foo/bar' and prefix '/foo' it was returning '/bar',
which is an absolute path. It was then constructing '-L${prefix}//bar'
with bogus double slash.
When subdir is '/fooo/bar' and prefix '/foo' it was returning 'o/bar'.
* Extend test_prefix_dependent_defaults unit test to cover default case
Extend test_prefix_dependent_defaults unit test to cover the default
case, when the default prefix is '/usr/local'. (On Windows, the default
prefix is 'c:/')
* Restore adjusting option defaults depending on the default prefix
Restore adjusting option defaults, depending on the default prefix.

There is a comment saying we do it because we used to do it. But it's
wrong and lead to using system library when cross compiling.
Factor out the code we use to find pkg-config, because it is the same
use-case.
The CMake config files / modules have to be checked
case insensitive in some cases, otherwise some dependencies
will not be found even though they are installed.
Instead of using dependencies as their own factories, which is rather
odd, lets just add a dedicated DependencyFactory class. This should be
able to take over for a lot of the factory type dependencies really
easily, and reduce the amount of code we have.
Currently PkgConfig takes language as a keyword parameter in position 3,
while the others take it as positional in position 2. Because most
dependencies don't actually set a language (they use C style linking),
using a positional argument makes more sense. ExtraFrameworkDependencies
is even more different, and duplicates some arguments from the base
ExternalDependency class.
For later changes I'm planning to make having all of the dependencies
use the same signature is really, really helpful.
Instead of checking the compiler id inside the VisualStudioLikeCompiler
class, this creates two subclasses that each represent the divergent
behavior of the two compilers
