QUICK START: Build Hercules Using CMake

To build Hercules on your computer using CMake, you need the following software installed:

• CMake version 3.4 or better: cmake --version. (CMake older than 3.4? See these instructions.)
• A git client version 1.8.5.1 or better: git --version.
• A c compiler. Both gcc and clang have been tested.
• If you wish to use 1Stop-Cmake, sed.
• A REXX interpreter, either Regina Rexx or Open Object Rexx, if you wish to run make test, the CMake equivalent of make check. 
• Not required: autoconf, automake, flex, gawk, grep, m4, nor perl. Although there is no issue if these are installed on the system being used to build Hercules-390.

Do the following to build Hercules using CMake on GNU/Linux or BSD open source systems or on Solaris.

1. Clone or update your local clone of Hyperion, as needed.
2. Create a build directory and make that directory your current working directory. You can create the build directory anywhere you wish, so long as the directory is writable.
3. Configure: cmake <hyperion-source-dir>
4. Build: cmake --build .
5. Run Tests: ctest
6. Install: cmake -P cmake_install.cmake      (if you wish)
