Update Eigen dependency to find installed version

[zachcran]

Is this pull request associated with an issue(s)?

No.

Description

CMaize uses find_package() in Config search mode to detect an installed version of a dependency. find_package in this mode looks for files named <PackageName>Config.cmake (case sensitive) or <lowercasePackageName>-config.cmake (also case sensitive, but lowercase). CMaize, by default, uses the dependency name provided to cmaize_find_or_build_dependency, which is eigen, but the Eigen package generates this file as Eigen3Config.cmake.

Solution

Use the optional NAME field in cmaize_find_or_build_dependency to set the correct find_package name to Eigen3.

TODOs

• Verify that this solution works with an installed version of Eigen (through Spack for me).
• Verify that this solution works when building Eigen from source.
• Verify that this solution works with sigma enabled as well. (Blocked by Error: CMake cannot specify compile definitions on installed Eigen target QCUncertainty/sigma#25)
• This depends on Update Eigen dependency to find installed version QCUncertainty/sigma#24, since it has the same issue and is a dependency of TensorWrapper.

Marked as draft until the issues in CMaize and sigma are resolved.

@ryanmrichard Can you rerun the failed test, please? There have been many changes since then that hopefully will fix the errors.
