Verify installation
clang-14 -v --cuda-path=/usr/local/cuda-10.2
sudo apt install libfmt-dev
cmake -DCMAKE_CXX_COMPILER=clang++-14 -DCMAKE_C_COMPILER=clang-14 -DCMAKE_INSTALL_PREFIX=/usr/local/fmt -Bbuild .

Add clang++ to path with:
sudo update-alternatives --install /usr/bin/clang clang /usr/bin/clang-14 140 --slave /usr/bin/clang++ clang++ /usr/bin/clang++-14
sudo update-alternatives --config clang++
Test with:
#include <cmath>
int main(){
return 0;
}
And clang++ -stdlib=libc++ vv.cpp
Add for an specific toolchain: --gcc-toolchain="/usr/lib/gcc/x86_64-linux-gnu/5
sudo add-apt-repository ppa:ubuntu-toolchain-r/test sudo apt install g++-11 gcc-11
