Installation from source failing

[figaro_]

Since the past few days the installation procedure from source is failing:

wget https://github.com/danmar/cppcheck/archive/refs/heads/main.zip
unzip main.zip
cd cppcheck-main
make MATCHCOMPILER=yes FILESDIR=/usr/share/cppcheck HAVE_RULES=no CXXFLAGS="-O2 -DNDEBUG -Wall -Wno-sign-compare -Wno-unused-function"

There are a few warnings and notes, but no errors. However:

$ cppcheck --version
Command 'cppcheck' not found, but can be installed with:
sudo apt install cppcheck

Have also tried with make install, sudo make install and followed various suggestions from https://stackoverflow.com/questions/27552188/how-do-i-install-cppcheck-using-the-tar-file-on-linux

$ gcc --version
gcc (Ubuntu 9.4.0-1ubuntu1~20.04.1) 9.4.0

Can someone explain the steps that I am missing?

I don't know it works for me. The PATH points at the path where the cppcheck binary is?
if you write the path explicitly it works better? ./cppcheck ?

Ok, it looks like the PATH needs to be updated as well. Thanks.
