[Symphony] Trouble compiling USER application

[Terry]

I installed pkg-config. Thanks for the info. But, the previous build issue that I reported still exists. That is, after 'make install', when I try to run bin/symphony it cannot find the library:

$ bin/symphony
dyld: Library not loaded: /testpkg/SYMPHONY-5.3.5/lib/libSym.3.dylib
  Referenced from: /testpkg/SYMPHONY-5.3.5/bin/symphony
  Reason: image not found
Trace/BPT trap

make is putting them here:

/testpkg/SYMPHONY-5.3.5/lib/coin/libSym.3.dylib
/testpkg/SYMPHONY-5.3.5/SYMPHONY/src/.libs/libSym.3.dylib

But not here where the program is looking:

/testpkg/SYMPHONY-5.3.5/lib/libSym.3.dylib

Copying the libraries there works.
