Since the changes of ef2b015e39 (Export CC and similar variables for
sub-configure scripts, 2018-10-20), using "-C" option with configure
didn't work any longer when also using built-in libtiff or expat, as
their configure scripts aborted due to detecting inconsistent build
environment because the values of exported CC etc variables they saw
differed from the values in the cache file.
Fixing this seems to be difficult, as we'd need to update the cache
before running the sub-configure scripts (which is simple enough), but
also remove the cached entries from it after doing it, as otherwise we'd
get the same inconsistent build environment problem simply by running
"configure -C" without any other options twice in a row, because the
first run would cache CC=gcc etc.
So work around this instead by disabling cache when exporting these
variables. And to make this workaround less annoying, restrict it to
only the cases when it's really needed, i.e. when we do modify these
variables in a non-trivial way.
With these changes, "configure -C" works again, but only uses caching if
possible.
About
wxWidgets is a free and open source cross-platform C++ framework for writing advanced GUI applications using native controls.
wxWidgets allows you to write native-looking GUI applications for all the major desktop platforms and also helps with abstracting the differences in the non-GUI aspects between them. It is free for the use in both open source and commercial applications, comes with the full, easy to read and modify, source and extensive documentation and a collection of more than a hundred examples. You can learn more about wxWidgets at https://www.wxwidgets.org/ and read its documentation online at https://docs.wxwidgets.org/
Platforms
This version of wxWidgets supports the following primary platforms:
- Windows XP, Vista, 7, 8 and 10 (32/64 bits).
- Most Unix variants using the GTK+ toolkit (version 2.6 or newer or 3.x).
- macOS (10.10 or newer) using Cocoa under both amd64 and ARM platforms.
Most popular C++ compilers are supported including but not limited to:

Licence
wxWidgets licence is a modified version of LGPL explicitly allowing not distributing the sources of an application using the library even in the case of static linking.
Building
For building the library, please see platform-specific documentation under
docs/<port> directory, e.g. here are the instructions for
wxGTK, wxMSW and
wxOSX.
If you're building the sources checked out from Git, and not from a released version, please see these additional Git-specific notes.
