App installation leads to cryptic precompile failures

[apozharski]

When using the juliac app (installed via ] app add or ] app dev) the installed shim contains:

export JULIA_LOAD_PATH="<HOME>/.julia/environments/apps/JuliaC"

Which makes the LOAD_PATH resolve to e.g. ["/home/anton/.julia/environments/apps/JuliaC"] which makes precompile fail as the new environment does not contain the required packages:

ERROR: The following 4 direct dependencies failed to precompile:

MadNLP

That's maybe a Pkg app issue? Did you set the --project for the build itself?

[apozharski]

This could indeed be a Pkg app issue, though from digging around in the issues on Pkg.jl this seems to be expected, though I am happy to raise an issue there instead.

And yes I set the --project for the build itself. The output above comes from calling:

juliac  --project .. --compile-ccallable --verbose --output-lib ./libMad ../src/libMad.jl

from libMad/build hence the relative paths. The same issue occurs when using absolute paths however.
