compilation clangXX

For now 1 or 2 weeks my automated compilation doesn’t work.
I checked and found error
CMake Error: your CXX compiler: "clang++" was not found. Please set CMAKE_CXX_COMPILER to a valid compiler path or name.


This is perhaps a side effect of the trials I do to compile another software (Kexi) ?

Could someone at least tell me which compiler should be used to compile Musescore ?

Thanks
