* Fix build error: `src/Backends/IF97/IF97Backend.h:54:34: error: call of overloaded ‘abs(double)’ is ambiguous`
Found with the manylinux_2_24_x86_64
gcc (Debian 6.3.0-18+deb9u1) 6.3.0 20170516
* Register MSVC 2019 and 2022 in setup.py
* setup.py: when calling cmake, build in parallel
* Enable using Env variables instead of passing them as args to setup.py
* Github actions for linux: try 1
* use actions/checkout@v3 for submodules
* mod setup.py:; typo
* Random shot for cibuildwheel for all platforms
* I thought package_dir was a flag, but it's positional
* typo in cmake_compiler
* add cython to setup_requires
* try a pryproject.toml to install cython
* try more requirements?
* pywin32 only found on win32 I guess
* Try with CIBW_BEFORE_BUILD instead
* try to enable msvc via vcvarsall on windows, and pass MACOSX_DEPLOYMENT_TARGET
* more tweaks for windoze
* disable tests for now (fails on windows)
* tweak mac again: it seems mac doesn't understand a C++ lambda, so like it's using pre C++11
* tweak
* try 10.15 for mac...
* try to force C++11 since mac picks up the path where lambdas are used...
* Move back down to 10.9 now that C++11 is enabled and it works on mac, it should be enough
* Try to debug win32
* Enable part of the upload step (minus the upload) to list the wheels
* try to allow win32 to fail for now (instead of plain disabling)
* Disable the python_linux.yml workflow, so cibuildwheels works fine.
* Adjust the upload step to point to the right folder
* make LGTM python happy
* initial commit
* got pressure unit tests working
* Added density solver and tests
* Added enthalpy function
* Added unit tests for S and G
* partial addition of flash
* PCSAFT backend implemented
