Hello,
I don't know enough to say whether this is an observation about deal.ii or
about Mac OSX (or maybe homebrew?), but the compiled binary of step-1 loads
around 100 system dynamic libraries:
```
$ DYLD_PRINT_LIBRARIES=1 ./step-1.release
....
```
This includes a bunch of things that seemingly shouldn't be required, such
as `libAudioStatistics.dylib`, etc.
The reason I care about this is that I think it adds around .25 seconds to
the application startup time, which is a very minor quality of life hit.
In fact, I can't see how to create a dealii binary that starts in less than
around a quarter second:
```
minimal.cc:
int main() {
return 0;
}
CMakeLists:
add_executable(minimal minimal.cc)
deal_ii_setup_target(minimal)
$ time builds/jackc-macos/minimal
builds/jackc-macos/minimal 0.24s user 0.01s system 98% cpu 0.255 total
```
As I say, I don't understand the issue well enough to know if there is
anything I or the deal.ii developers can do about it! In any case, 0.25s is
a very small price to pay for so much functionality and expressiveness.
Thank you,
-Jack
