Hi Wakil,
so command line tools are installed, did you check?
CMake tells you the error:
The CMAKE_C_COMPILER:
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.
xctoolchain/usr/bin/cc
is not a full path to an existing compiler tool.
so see whether you have this or not. Perhaps something changes in between
macOS versions, I won't be surprized. The dmg you download are built with
specific version (probably Sierra or High Sierra) using Apple's clang. So
if location of compiler changes between those versions, then there is a
problem.
Regards,
Denis
