Solution

Unable to build C SCM 1.0.2.783 on Windows with C SDK 3.1.0.

Workaround: In the twCSdk.cmake file, replace

set(twcsdk_runtime_libs_windows

else()
set(twcsdk_runtime_libs_windows
"${thingworxLibsDir}/twCSdk.dll"
"${thingworxLibsDir}/libcrypto-l_l.dll"
"${thingworxLibsDir}/libssl-l_l.dll" )
endif()
