Hello,

I encountered an error saying that Imath wasn't in any export set when adding Imath and Alembic by add_subdirectory(), so I made a change exporting Imath from a build tree and making each file path of ImathConfig.cmake.in and ImathConfigVersion.cmake exact.
However, this PR requires the following code

file(WRITE "${CMAKE_CURRENT_BINARY_DIR}/config/ImathTargets.cmake" "# Dummy file")

and I can't understand the reason. So, if anyone have a better way, please feel free to tell me.

make each file path of ImathConfig.cmake.in and ImathConfigVersion.cmake exact.

Thanks for spotting this issue. It looks good to me, we just need someone to check that it works with our internal builds.

@meshula, I've built OpenEXR against this change, both as an external installation and an internal build, and both succeed, as does the CI. What other checks were you imagining to validate the "internal builds"?

Nothing special, I just wanted to give space for studios such as yours to make sure it doesn't impact your internal build.

## Version 3.1.10 (January 26, 2024)

Patch release with various build/bug fixes.

Build fixes:

  - Fix a problem where downstream projects using Imath would build
    python bindings even if they weren't requested.
  - Fix for missing `std::bit_cast`
  - Fix missing/necessary use of IMATH_HOSTDEVICE
  - IMATH_INSTALL_PKG_CONFIG is now on by default, even on Windows
  - Fix calling default constructor by uniform init in TypeTraits
  - Fix redundant PYIMATH_EXPORTS causing compile issues on Windows Clang
  - Update to SO versioning policy:

    This change adopts a policy of appending the ``MAJOR.MINOR.PATCH``
    software release name to the ``SONAME`` to form the real name of the
    shared library.

    See [website/install.rst](website/install.rst) and [PR
    #339](AcademySoftwareFoundation/openexr#339)
    for more details.

Bug fixes:

  - Fix half to float giving wrong results on older x86_64 CPUs on Windows

Other changes:

  - succ()/pred() now use std::nextafter().
  - Expand epsilon bounds for m44x pyImath test.
  - Rename "docs" to "website".
  - Add missing copyright/license identifiers.
