Get Ipopt binaries

• Get the md variant from https://github.com/coin-or/Ipopt/releases/tag/releases%2F3.13.3
• Unpack into some place like C:\Users\me\Ipopt-3.13.3-win64-msvs2019-md (this should contain a subfolder named Ipopt-3.13.3-win64-msvs2019-md)

Compile CasADi

Goal: get a VS-compatible IPOPT-enabled CasADi installation in C:\Users\me\casadi_install.

• Get a copy of CasADi source, e.g. from https://github.com/casadi/casadi/archive/refs/tags/3.5.5.zip and unpack it in a folder.
• In that same source folder (check that README.md exists to be sure you are in the correct folder), create a run.bat with the following contents:

@echo Must be run in a prompt context that defines vcvars.
@echo For example in 'x64 Native Tools Command Prompt for VS 2019'

cmake -G "Visual Studio 16 2019" -A x64 -B build -DWITH_IPOPT=ON -DIPOPT_LIBRARIES:FILEPATH="C:/Users/me/Ipopt-3.13.3-win64-msvs2019-md/Ipopt-3.13.3-win64-msvs2019-md/lib/ipopt.dll.lib" -DIPOPT_INCLUDE_DIRS:PATH="C:/Users/me/Ipopt-3.13.3-win64-msvs2019-md/Ipopt-3.13.3-win64-msvs2019-md/include/coin-or"  -DCMAKE_INSTALL_PREFIX:PATH="C:/Users/me/casadi_install"
cmake --build build --config Release
cmake --install build

• Run this file inside a "x64 Native Tools Command Prompt for VS 2019" from within that same source folder.

Compile a CasADi C++ example

Goal: get a casadi_demo.exe to run succesfully.

• Make a local copy of https://github.com/casadi/casadi/tree/3.5.5/docs/examples/cplusplus/cmake_find_package
• Add an extra line install(TARGETS casadi_demo RUNTIME DESTINATION . LIBRARY DESTINATION .) to CMakeLists.txt if absent.
• Create a run.bat with the following contents:

@echo Must be run in a prompt context that defines vcvars.
@echo For example in 'x64 Native Tools Command Prompt for VS 2019'
set CMAKE_PREFIX_PATH=C:\Users\me\casadi_install

cmake -G "Visual Studio 16 2019" -A x64 -B build -DCMAKE_INSTALL_PREFIX:PATH="."
cmake --build build --config Release
cmake --install build

set PATH=%PATH%;C:\Users\me\casadi_install\casadi;C:\Users\me\Ipopt-3.13.3-win64-msvs2019-md\Ipopt-3.13.3-win64-msvs2019-md\bin

casadi_demo.exe

• Run this file inside a "x64 Native Tools Command Prompt for VS 2019"
