Adding building using CMake (#81)

This commit adds an option to build using CMake by adding
CMakeLists.txt. CMake builds are consistent with the builds currently
produced.

For Linux build, CPack produces artifacts consistent with the current
RPM specification.

CMake is also added to the CI pipeline in main.yml.

-## Building with clang++ on Linux, OS/X, *BSD, etc.
-Install clang through your package manager (most systems), Xcode (OS/X), or from the [LLVM website](http://llvm.org/releases/).
-On Linux, you also need to install recent GNU's "libstdc++" or LLVM's "libc++".
-
-Run `make` to build the `pict` binary.
-
-Run `make test` to run the tests as described above (requires Perl).
+## Building on Linux, OS/X, *BSD, etc.
+PICT uses CMake to build on Linux.
+Assuming installation of CMake and C++ toolchain, following set of commands will build and run tests in the directory `build`
