Hi.
I’ve got an issue that is reported in the following github issues:
opened 05:36PM - 14 Sep 23 UTC
type:Bug
### Description
I tried to build `itk-wasm` after having built `ITK`. It fail… s at the `cmake ..` step since it cannot find `ITKModuleExternal.cmake`. The issue has been reported here:
https://github.com/InsightSoftwareConsortium/itk-wasm/issues/933
### Steps to Reproduce
Build `ITK` on Ubuntu 22 with `cmake .. && make && sudo make install` and then build `itk-wasm` with `cmake ..`. Here are the revisions:
`ITK`: `aaa43159aa5510fd514c71823b6b9c86b1f01212``
`itk-wasm`: `b1289e36d0b2483c8687d9325fb16ed604be4b15`
### Expected behavior
The `itk-wasm` build would pass the `cmake ..`step.
### Actual behavior
It fails to find `ITKModuleExternal.cmake`. Log is here:
https://github.com/InsightSoftwareConsortium/itk-wasm/issues/933
### Reproducibility
Deterministic.
### Versions
Revision SHAs have been given above.
### Environment
Ubuntu 22 on an amd64.

I just built ITK from source with `cmake ..`and `make` followed by `sudo make in… stall`. I hoped to pull all ITK dependencies this way. It appears not:

This is likely a problem in ITK itself, but as it impacts itk-wasm, it seems not incorrect to open an issue here.
Roughly put: I am trying to build ITK and itk-wasm from source, living on the git repo head. The ITKModuleExternal.cmake file is supposed to come from ITK and to be consumed by itk-wasm. However, nothing I try with the usual cmake procedure manages to get this ITKModuleExternal.cmake file published. It hence is not consumed by itk-wasm.
What is the known, standard and/or documented way to get this done ? Or should I resort to manual or not-so-manual hacks ? Seems to me like a cmake configuration issue in ITK repo.
Please advise.

ITK itself builds fine, and is thoroughly tested. The issue most likely comes from itk-wasm’s build system, or the way you are invoking it. @matt.mccormick might know more.
Hi,
In summary, the file ITKModuleExternal.cmake ’s purpose to to enabling an ITK module that lives in a repository separate from ITK, to be built against an ITK build tree. It is intentionally not added to the install tree.
