Configure config.h and include it from the build directory.
- Previously we overwrote the default (empty) config.h in the source
tree with a configured config.h, generated using the current compile
options.
- This was undesirable as it could lead to inadvertant commits of the
generated config.h.
- This patch moves the default config.h to <src>/config/ceres/internal,
separate from the other headers, thus if Ceres is compiled without
CMake this directory will now also have to be included. This
directory is _not_ added to the CMake include directories for Ceres
(thus the default config.h is never used when compiling with CMake).
- When using CMake, the generated config.h is now placed in
<build>/config/ceres/internal, which is in turn added to the include
directories for Ceres when it is compiled, and the resulting config.h
is copied to ceres/internal when installed.
