Applications fail to install in `bin` on Windows

[ischoegl]

Problem description

While the post-install message claims to install applications in

[...]
postInstallMessage(["finish_install"], [])

Cantera has been successfully installed.

File locations:

  applications                C:\Users\<user>\cantera\bin
  library files               C:\Users\<user>\cantera\lib
  C++ headers                 C:\Users\<user>\cantera\include
  samples                     C:\Users\<user>\cantera\samples
  data files                  C:\Users\<user>\cantera\data
  Python package (cantera)    C:\Users\<user>\miniconda3\envs\cantera-dev\Lib\site-packages
  Python samples              C:\Users\<user>\miniconda3\envs\cantera-dev\Lib\site-packages\cantera\examples
scons: done building targets.

nothing is installed in cantera\bin (the folder is actually not even created). While this may be a limitation of the OS, the post-install message is pointing at an issue.

Steps to reproduce

Compile & install Cantera from source.

System information

• Cantera version: 2.6.0a4
• OS: Windows 10
• Python/MATLAB/other software versions: Python 3.9 from miniconda (see toolchain)

I'm removing the Applications line in "add package workflow" #1158 and replacing it with the location of the converter scripts read from pip, which should be correct (one hopes...).

[ischoegl]

That should work (🤞) ... this came up in #1191 btw

fwiw, the current installation location is C:\Users\<user>\miniconda3\envs\cantera-dev\Scripts

[ischoegl]

Interestingly, this doesn't affect installations where conda is used (the install location is correct). On the other hand, the issue persists when a user-defined prefix is specified.

On further inspection, things end up in the conda folder despite specifying prefix as a different location ...
