Cross Compilation with CMake

[slamer59]

Cmake is designed to build, test and package software.
Add a cmake to streamline the code generation for multiple platforms is an approach

CoolProp developpement shows how to build static library from it

The same approach can be seen here

Compiled library will be installed in Resources/Library following suggestion #4 (comment).

I guess this one is obsolete soon since #6 already contains my changes that introduced CMake. However, my code was written in a hurry and I would appreciate if you had a look at it.

It is a good starting point to reach the objective by the end of the year.

For an enhancement, all commands in .bat file and .sh in ExternalMedia/Projects/ may be integrated in CMakeLists.txt. It will be easier to maintain one file for cmake than 10 specific files for specific compilation.

We can build a more robust cross compilation process integrating all those command in CMake:

• FindGit.cmake helps to find git and will replace all commands like git clone, git pull,...
• CFLAGS will replace for example C_OPTS, i.e. GCC_OPTS, variable in .bat file, .i.e .sh file
• file(COPY ${CMAKE_CURRENT_SOURCE_DIR}/ DESTINATION ${CMAKE_CURRENT_BINARY_DIR}) to replace copy or cp command
• ...

I guess all specific compilation option will be handle by hand or by TravisCI system.

Yes, but we still have to decide whether we want to use CoolProp as a submodule in git or as an external CMake project (ExternalProject_Add). I think we should try to avoid calling git manually :-)

@jowr, I think this is not related to CMake
So I open a specific subject #8
