Building Audacity on Mojave

I have been building Audacity for a number of years and moved to using the new Cmake build process when that was initiated. That process now fails every time during the configuration process with the same errors. The one that seems to finally kill the config process is:

WARN: wxwidgets/ requirement expat/2.2.9 overridden by your conanfile to expat/2.2.9@audacity/stable
libmp3lame/3.100: ERROR: Error downloading binary package: ‘libmp3lame/3.100:b0aaa809c473836ac14ba3ba95f6ebea6e1f1f5f’
ERROR: HTTPSConnectionPool(host=‘’, port=443): Max retries exceeded with url: /v1/ping (Caused by SSLError(SSLCertVerificationError(1, ‘[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: certificate has expired (_ssl.c:1129)’)))

Any ideas to get around the problem?
The configuration command I use is: cmake -G Xcode … 2>&1 | tee CmakeCnfg.log

I’ve attached the whole CMakeCnfg.log file. It’s quite short.
CmakeCnfg.log (11.3 KB)

The best place to ask about build issues is on the Audacity Dev discord channel - there’s a section for:
“Compiling Audacity > macOS”
Here’s an invite to the channel:

Thanks Steve. Will go there.
