# Build test for the Paho C++ library.
#
# This test the build with a few compilers on Linux. It does a build using 
# CMake, for the library, tests, and examples, then runs the unit tests.
# This is repeated for each of the compilers in the list. If a particular 
# compiler is not installed on the system, it is just skipped.
#
# This is not meant to replace Travis or other CI on the repo server, but
# is a quick test to use locally during development.
