V4 header install devel

[lucjaulmes]

#614 fixing #611 rebased on devel, and without changing include paths. (Does not require foreach anymore).

Creates some quirky layout of files but all headers are under $prefix/include and quest.h can be included as #include "quest.h" (which required updating some of the deprecated test paths which were trying to include quest/include/quest.h).

Example with verbose installing to /tmp/cmake:

-- Install configuration: "Debug"
-- Installing: /tmp/quest/bin/min_example
-- Set non-toolchain portion of runtime path of "/tmp/quest/bin/min_example" to "$ORIGIN/../lib64"
-- Installing: /tmp/quest/lib64/libQuEST-fp1+mt.so.4.0.0
-- Installing: /tmp/quest/lib64/libQuEST-fp1+mt.so.4
-- Set non-toolchain portion of runtime path of "/tmp/quest/lib64/libQuEST-fp1+mt.so.4.0.0" to "$ORIGIN/../lib64"
-- Installing: /tmp/quest/lib64/libQuEST-fp1+mt.so

-- Installing: /tmp/quest/lib64/cmake/QuEST/QuEST-fp1+mtConfigVersion.cmake

And without verbose naming, defines aren’t set in cmake files anymore but in quest.h directly:

-- Install configuration: "Debug"
-- Installing: /tmp/quest/bin/min_example
-- Set non-toolchain portion of runtime path of "/tmp/quest/bin/min_example" to "$ORIGIN/../lib64"
-- Installing: /tmp/quest/lib64/libQuEST.so.4.0.0

Thanks Luc! @TysonRayJones this looks good to me :)

[TysonRayJones]

Brilliant, thanks very much! You raised fair points in the other PR - I hope my preferences about the include paths haven't resulted in something horribly non-standard! I accept full blame 😌
