我想安装 wxmaxima，所以我从源下载了文件并尝试按照安装步骤操作。我遇到一个问题，说当前版本的 wxWidgets 版本太旧了，需要 3.0.0 版本。我下载了它的最新版本。我想我安装正确了，这是输出。
The installation of wxWidgets is finished.On certain
platforms (e.g. Linux) you'll now have to run ldconfig
if you installed a shared library and also modify the
LD_LIBRARY_PATH (or equivalent) environment variable.
wxWidgets comes with no guarantees and doesn't claim
to be suitable for any purpose.
Read the wxWindows Licence on licencing conditions.
然后我尝试安装 wxmaxima，输出仍然一样，就好像我没有安装新版本的 wxWidgets 一样。
wxmaxima 的 ./configure 命令的输出是：
checking for wxWidgets version >= 3.0.0... no (version 2.8.10 is not new
enough)
configure: error:
wxWidgets must be installed on your system.
Please check that wx-config is in path, the directory
where wxWidgets libraries are installed (returned by
'wx-config --libs' or 'wx-config --static --libs' command)
is in LD_LIBRARY_PATH or equivalent variable and
wxWidgets version is 3.0.0 or above.
