Issue
I followed the guide in the page linphone-sdk and also run these with the MSYS2 MSYS command in Windows 10:
pacman -S mingw-w64-i686-cmake
pacman -S mingw-w64-i686-ninja
pacman -S p7zip
My PATH variable contains these:
...C:\msys64;C:\msys64\usr\bin;C:\msys64\mingw32\bin;C:\msys64\mingw64\bin;C:\msys64\usr\lib\p7zip;...
Then I run the configuration command:
cmake -DENABLE_AAUDIO=OFF -DENABLE_ADVANCED_IM=NO -DENABLE_AMRNB=OFF -DENABLE_AMRWB=OFF -DENABLE_ASSETS=NO -DENABLE_BV16=NO -DENABLE_CAMERA2=OFF -DENABLE_CODEC2=OFF -DENABLE_CSHARP_WRAPPER=OFF -DENABLE_CXX_WRAPPER=NO -DENABLE_DB_STORAGE=NO -DENABLE_DEBUG_LOGS=YES -DENABLE_DOC=OFF -DENABLE_EMBEDDED_OPENH264=OFF -DENABLE_FFMPEG=OFF -DENABLE_G726=OFF -DENABLE_G729=OFF -DENABLE_G729B_CNG=OFF -DENABLE_GPL_THIRD_PARTIES=NO -DENABLE_GSM=NO -DENABLE_GTK_UI=OFF -DENABLE_H263=OFF -DENABLE_H263P=OFF -DENABLE_ILBC=OFF -DENABLE_ISAC=OFF -DENABLE_JAVA_WRAPPER=OFF -DENABLE_JAZZY_DOC=OFF -DENABLE_JPEG=NO -DENABLE_LIME=OFF -DENABLE_LIME_X3DH=NO -DENABLE_MBEDTLS=YES -DENABLE_MDNS=OFF -DENABLE_MKV=NO -DENABLE_MPEG4=OFF -DENABLE_NLS=OFF -DENABLE_NON_FREE_CODECS=OFF -DENABLE_OPENH264=OFF -DENABLE_OPUS=NO -DENABLE_PCAP=OFF -DENABLE_POLARSSL=OFF -DENABLE_QRCODE=OFF -DENABLE_RTP_MAP_ALWAYS_IN_SDP=OFF -DENABLE_SILK=OFF -DENABLE_SOCI_MYSQL=OFF -DENABLE_SPEEX=YES -DENABLE_SQLITE=YES -DENABLE_SRTP=NO -DENABLE_SWIFT_WRAPPER=OFF -DENABLE_TOOLS=NO -DENABLE_TUNNEL=OFF -DENABLE_UNIT_TESTS=NO -DENABLE_UNMAINTAINED=OFF -DENABLE_UPDATE_CHECK=OFF -DENABLE_V4L=OFF -DENABLE_VCARD=NO -DENABLE_VIDEO=NO -DENABLE_VPX=OFF -DENABLE_WASAPI=ON -DENABLE_WEBRTC_AEC=YES -DENABLE_WEBRTC_AECM=YES -DENABLE_WEBRTC_VAD=OFF -DENABLE_X264=OFF -DENABLE_XML2=NO -DENABLE_ZLIB=NO -DENABLE_ZRTP=NO -DENABLE_ZRTP=OFF ..
and then the build command:
cmake --build .
I got following build errors (contains from the build log the parts where are the word "failed"):

It seems that the real error is this:
I'm not sure what is the cause of the error message:
error: missing binary operator before token "("
Here What does the compiler error "missing binary operator before token" mean? is some definition about the error, but I'm not sure why the error happens. Does it happen only in the specific environment??
Solution
When I configured my environment according to the https://gitlab.linphone.org/BC/public/linphone-sdk/ page and used the Developer Command Prompt for VS 2017 the build seems to go through.
