Missing headers when installed

[brettviren]

Running edep-sim from an in-source build of master seems to allow an error free run.

Running it from an installed location leads to errors due to missing headers. The installation I'm testing is created using spack install edepsim@master using the Spack fork in my GitHub area. But, I think this problem is unrelated to Spack per se but rather due to running from an installation location other than where the build occurred.

Here is the error output:

The job does actually complete and a quick check of the output ROOT file shows no immediate problems but I've yet to get edep-disp (which also gives errors like the above) to show meaningful results on the file.

That path referenced in the error is a temporary build area and doesn't exist after installation. It looks like something in the build is baking-in this path.

FWIW, setting ROOT_INCLUDE_PATH to point at directories in a copy of edep-sim source doesn't help.

Even with -inlineInputHeader as added in #2, one needs to set ROOT_INCLUDE_PATH (to in-source location of includes for now) or else edep-sim gives complaints like:
