1. We put all shared libraries into one place. Both conan and locally built
2. We invoke CopyLibs to copy the libraries to a proper location and to correctly set the RPATH
Fixes CopyLibs script on Windows
Fixes CopyLibs.cmake for Linux
Fixes CopyLibs on macOS

A special mode `audacity_obey_system_dependencies` is added, so the build will fail if we could not build against a system package for some reason.
The following packages are marked for the local build now:
* **wxWidgets**: Ubuntu lacks support for 3.1.3. We can't build against 3.0 branch.
* **portaudio**: there are issues, that prevent using a system version of portaudio.
* **sqlite3**: Ubuntu package is very dated; we care about the performance and stability.
* **nyquist**: Ubuntu has no package available.
* **vamp**: Ubuntu has no development package available.
* **portmixer**: Ubuntu has no package available.
* **sbsms**: Ubuntu package is very dated; we care about the performance and stability.
We use docker to create a clean build environment. Currently, `pkg-config` is used to locate the system libraries. There are few issues with `pkg-config` on Ubuntu:
* It does not work with `lame` and `portmidi`.
* The packaged files for `id3tag` and `mad` have wrong version.
We fix such cases by copying the
into `/usr/local/lib`.
... not assuming that it is invoked from cmake-proxies/CMakeLists.txt
This will allow modules to use lib-src libraries, and even for a module to be
the sole user of one of them.
So addlib lines may be moved out of cmake-proxies/CMakeLists.txt, when no
longer needed to build the reduced executable without the modules.
... So mod-foo defines FOO_API properly on the command line, for use in its
public header files; on Windows, appropriately expanding one way when compiling
the library, another way when compiling other code that uses it, so that all
will link correctly.
And added a python version that will be used on all platforms
when a suitable msgfmt isn't installed. (As long as python
is installed.)
Extracted all the Audacity specific functions from main cmake
list and moved them to their own module.
Rearrange the main cmake module a bit and misc. cleanup.
