Here is the warning currently being produced:
CMake Warning (dev) at C:/Program Files/CMake/share/cmake-3.19/Modules/GNUInstallDirs.cmake:223 (message):
Unable to determine default CMAKE_INSTALL_LIBDIR directory because no
target architecture is known. Please enable at least one language before
including GNUInstallDirs.
Call Stack (most recent call first):
I noted how I fixed the error. This is caused by GNUInstallDirs automatically executing code just by including it.
I also added -Werror=dev to the CI to ensure this never happens again.

* Cmake Revamp
I needed to do a variety of things to ensure cxxopts worked well in my own project.
I created a new cmake module to abstract a lot of the logic in the main CMakelists.txt, I think it really assists in the readability of the project. Consequently a lot of logic is now written in functions.
I made a lot of the project options off by default unless the project is being built standalone. As a frequent consumer of cmake libraries this is a huge issue. Since examples, tests, installation, etc. aren't things I expect/desired by default when using libraries.

Major refactor of the parsing code organisation to improve encapsulation
and not modify the input arguments. The returned result no longer has
pointers into the original option specification.
* Fixes#245:
* Added a new exception type: `option_has_no_value_exception`; throwing it when an option has no value we can cast with `as()`, instead of an `std::domain_error`.
* The `OptionValue` type now holds a pointer to the long option name (in its corresponding key within ParseResults's `m_results` field.
This speeds up the CMake configuration step by not searching for a C
compiler. By default, CMake looks for C and C++ compilers, unless a set
of compilation languages is specified.
Some positional parameters would be listed in the help text and others
would not, when what is desired is that no positional parameters are
listed with the other command options. This change suppresses the help
listing for all positional parameters.
