CMakeList.txt assumes gcc is /usr/bin/g++ and clang is /usr/bin/clang++

[mpmilano]

It looks like the project's root CMakeLists.txt makes assumptions about where clang and GCC are installed which doesn't match all configurations / distributions. In particular, I'm referring to the conditionals which guard appending "-pthread" (and other flags) to the CMAKE_CXX_FLAGS_COMMON variable. The fix is likely as simple as changing the conditional guard by replacing instances of ${CMAKE_CXX_COMPILER} STREQUAL "/usr/bin/clang++" with ${CMAKE_CXX_COMPILER_ID} MATCHES "(C|c?)lang" (and similar for GCC).

The valid values of CMAKE_CXX_COMPILER_ID can be found here
