Once CMake has a usage hash, there may be a way to use the hash CMake uses for the `.bmi` names of imported modules with some cache.

There's a stubbed out [`cmCxxModuleUsageEffects.cxx`](https://gitlab.kitware.com/cmake/cmake/-/blob/87f270800cb675f0e1e4e3a6419a8f5b79afdae4/Source/cmCxxModuleUsageEffects.cxx) file that is intended to determined when an import of a module can be reused. Right now it assumes that all uses are compatible, so...

FWIW, I have this script as well: ```sh #!/bin/sh set -e readonly profile="$1" shift exec xargs \ restic backup \ --password-file "$XDG_CONFIG_HOME/restic/$profile.pass" \ --tag "$HOSTNAME" \ --tag "$profile" \ <...

No, that change only affects build time. I'll take a look here.

3.28.0 with a minimal build on Windows and Linux both install what seem to be the correct file: ```commands > c:\Users\ben.boeckel\code\cmake\build\bin\cmake.exe -GNinja ..\src -DCMAKE_INSTALL_PREFIX=c:/Users/ben.boeckel/code/itk/build/install -DITK_BUILD_DEFAULT_MODULES=OFF -DENABLE_TESTING=OFF -DModule_ITKEigen3=ON -DWITH_GTEST=OFF -DZLIBNG_ENABLE_TESTS=OFF -DITKGroup_Core=OFF...

Is it somewhere else in the install tree?

> cmake.exe ..\src -DCMAKE_INSTALL_PREFIX=\path\install2 -DBUILD_TESTING=OFF This, using the Visual Studio generator also ends up with files installed properly. Can you please check whether the `ITKInternalEigen3-build/cmake_install.cmake` code has a reference to...

It's being installed by that script at least. Something else seems to be interfering. Can you save off the install logs and see if got installed at one point and...
