HermitCore CMake build system
HermitCore requires at least CMake version 3.7, which (at the time of
introduction) is not yet available on most Linux distributions. We therefore
provide a script cmake/local-cmake.sh that fetches precompiled binaries from
the CMake project and installs them locally in cmake/cmake-3.7*. Only when
sourced for the first time it will download CMake, on further runs it detects
the existing download and adds it to PATH automatically.
$ . cmake/local-cmake.sh
-- Downloading CMake
cmake-3.7.2-Linux-x 100%[=================>] 29,26M 837KB/s in 19s
-- Unpacking CMake
-- Local CMake v3.7.2 installed to cmake/cmake-3.7.2-Linux-x86_64
-- Next time you source this script, no download will be neccessary

Additional language support
Currently, HermitCore supports C, C++, Fortran, Go through Cmake. While the
former are supported and detected by CMake out-of-the-box, Go support has been
added manually for HermitCore.
Adding a new language requires you to provide CMake hints where to find the
toolchain and then how to compile and link binaries. The Go support in
cmake/golang may serve as an example on how to add a new language.
To finally enable the language it has to be added to CMake's module path in
cmake/HermitCore.cmake:
# scripts to detect HermitCore Go compiler
list(APPEND CMAKE_MODULE_PATH ${CMAKE_CURRENT_LIST_DIR}/golang/)
# scripts to detect new language
list(APPEND CMAKE_MODULE_PATH ${CMAKE_CURRENT_LIST_DIR}/new-language/)
User applications
You just have to include HermitCore-Application.cmake before the project()
command in your CMakeLists.txt in order to build applications for HermitCore.
For configuration parameters of the project, please consult the README.md in
the root of this repository.
